Some cats can be trained to jump from one location to another and perform other tricks. Kit the cat is going to jump through a hoop. He begins on a wicker cabinet at a height of 1.770 m above the floor and jumps through the center of a vertical hoop, reaching a peak height 3.105 m above the floor. (Assume the center of the hoop is at the peak height of the jump. Assume that +x axis is in the direction of the hoop from the cabinet and +y axis is up. Assume g = 9.81 m/s².) (a) With what initial velocity did Kit leave the cabinet if the hoop is at a horizontal distance of 1.577 m from the cabinet? (Express your answer in vector form. Give your answer to at least two decimal places for each vector component.) Vo = m/s (b) If Kit lands on a bed at a horizontal

Problem 2: In baseball the pitcher will throw baseballs horizontally and to account for gravity, the pitcher will stand upon a raised mound. Take the pitcher's release point to be 1.2m above the ground and they will hit a spot 0.7m above the ground at a distance 20m away. a) Draw ST vs t, sy VS t, Uz VS t,, Vy vs t, a vs t,, and ay vs t, graphs of the baseball's motion b) from Kinematic Equations on the first page Prove that the velocity needed is = 9(Asz)² V24sy symbolically by starting c) If the pitcher was playing on Mars (g = 3.7m/s, negligible air resistance) how fast would they have to pitch?
Danielle launches a ball off of a platform of height h with velocity vo at an angle 0 above the horizontal. A wall with a ball-sized hole a height H above the floor, with H > h, is a horizontal distance L = 24.0 m away from Danielle. The difference in height between H and h is one-twelfth of L, and the square of the magnitude of the velocity, v, is three-halves of the product gL. H 1 H – h = h 3 L Determine the two values of 0 that ensure the ball passes through the hole. Submit the larger angle as 0, and the smaller angle as 02.

Children playing in a playground on the flat roof of a city school lose their ball to the parking lot below. One of the teachers kicks the ball back up to the children as shown in the figure below. The playground is 5.60 m above the parking lot, and the school building's vertical wall is h = 6.90 m high, forming a 1.30 m Ngh railing around the playground. The ball is launched at an angle of 0 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Find the speed (in m/s) at which the ball was launched. m/s (b) Find the vertical.distance (in m) by which the ball clears the wall. (c) Find the horizontal distance (in m) from the wall to the point on the roof where the ball lands. (d) What If? If the teacher always launches the ball with the speed found…
