- A trapper walks a 5.0-km straigt4ine distance from his cabin to the lake, as shown in the following figure. Use a graphical method (the parallelogram rule) to determine the trapper’s displacement directly to the east and displacement directly to the north that sum up to his resultant displacement vector. If the trapper walked only in directions east and north, zigzagging his way to the lake, how many kilometers would he have to walk to get to the lake?arrow_forwardThis is a two part problem. If you drive your car for 30 miles to the west, then 20 miles north of east at 60 degrees and then 5 miles south: A. What is the displacement of your car from the origin in unit vector notation? Draw a diagram to go along with your answer. B: What is the magnitude and direction of the displacement?arrow_forwardSuppose you walk 15 m straight west and then 29 m straight north as shown in the figure: a.) How far are you from your starting point in meters? b.) What is the angle of displacement measured west of north in degrees?arrow_forward
- An automobile traveling 95km/h overtakes a 1.30 km long train traveling in the same direction on a track parallel to the road. If the train’s speed is 75km/h. (a) how long does it take the car to pass it?, and (b) howfar will the car have traveled in this time? See diagram. (c) What are the results if the car and train are traveling in opposite directions? ( Show your work).arrow_forwardIf a baseball is hit with a vertical speed of 20 m/s and a horizontal speed of 4 m/s, how long will the ball remain in the air? (Assume for the purposes of this question that the ball starts at nearly ground level.) ______ s How far wil it go? ______ m ***Please write down work. Thank you! Trying to learnarrow_forwardA student bikes to school by traveling first N = 1.00 miles north, then W = 0.400 miles west, and finally S = 0.200 miles south. a. If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance would the bird cover? b. Finally, find ϕ, the angle north of west of the path followed by the bird.arrow_forward
- I need magnitude and direction of D of the displacement from start to finish explain please.arrow_forwardBruce begins 7 kilometers to the north of town and rides his bike along a straight trail which leads to a park 3km west of town. It takes him 20 minutes to cover this distance. Write a vector in component form that describes his ride while also finding the magnitude and direction of this vector. Also, find the component of Bruce's motion which is in the direction of SW using a unit vector that uses both forms of the dot product (algebraic and geometric), then write parametric equations expressing his motion with the town being represented by the origin and t=0 being his starting point. Using these equations, what is his position after 5 minutes? Then eliminate the parameter to get a rectangular equation for this linear path and verify algabraically amd graphically that this equation represents the line.arrow_forwardA chameleon is resting quietly on a lanai screen, waiting for an insect to come by. Assume the origin of a Cartesian coordinate system at the lower left-hand corner of the screen and the horizontal direction to the right as the +x -direction. If its coordinates are (2.000 m, 1.000 m), (a) how far is it from the corner of the screen? (b) What is its location in polar coordinates?arrow_forward
- Which of the following graphs do you expect to find for the puck's x-velocity as it travels down and then back up the ramp? Assume the puck starts its motion at x = 0, and the +x axis points down the ramp. Choose one answer: A,B, C or D. Explain which one you chose and explain your reasoning in a couple of sentences. Which of the following graphs do you expect to find for the puck's x-position as it travels down and then back up the ramp? Assume the puck starts its motion at x = 0, and the +x axis points down the ramp. Choose one answer: A,B, C or D.

His velocity graph is shown below. Answer the following: d) How far does the player move to the right? What is the player’s ending position as relative to the starting position? e) Sketch a motion diagram of the player in the 12 seconds of motion using a position reference frame. Give proper labels.arrow_forwardA rock is thrown upward from level ground in such a way that the maximum height of its flight, ymax, is equal to its horizontal distance d it travels before landing. (a) At what angle theta is the rock thrown? (b) Would your answer to part (a) be different on a different planet? Why? Hint for part (a): Make a sketch. Write out separate equations for vertical and horizontal motion, introducing a time variable. Relate the two equations to solve for theta.arrow_forward
