- Is it possible for speed to be constant while acceleration is not zero? Give an example of such a situation.In a classic clip on Americas Funniest Home Videos, a sleeping cat rolls gently off the top of a warm TV set. Ignoring air resistance, calculate the position and velocity of the cat after (a) 0.100 s, (b) 0.200 s, and (c) 0.300 s.I am driving at 35 mph on a foggy day when I see a car 5 miles ahead of me stopped in the road with its hazard lights on. I can accelerate my car at about -12 mph/s. How long do I have to decide if I will need to swerve to avoid hitting the car? Which is the correct equation to use
- IT IS POSSIBLE FOR THE SPEED OF AN OBJECT TO BE ZERO AT THE SAME TIME THAT ITS ACCELERATION IS NOT ZERO. GIVE AN EXAMPLE OF SUCH SITUATION.Is this statement true or false? and why? If an object is speeding up, its acceleration must be positive.Which of the following represents a negative acceleration? Select all apply. An object is at rest An object is moving to the right with a constant speed An object is moving to the right and speeding up An object is moving to the right and slowing down An object is moving to the left with a constant speed An object is moving to the left and speeding up An object is moving to the left and slowing down
- I am currently learning about kinematics in my physics class. For one of the questions, it asks me to solve a question that asks me to find the magnitude of acceleration. I have found answers ranging between 3 and 4, but everytime I put my answer into Webassign it is wrong. I was wondering how I would find the magnitude of acceleration given the time and distance. Thank youDoes acceleration depend on the speed of an object? Why or why not? Give an example of a slow object having a larger acceleration than a fast object. Can anyone think of an example of an object moving in such a way so that it is accelerating while having zero velocity?If an object travels at a constant velocity, what can we say about its acceleration? What is another situation where an object could have no acceleration? When solving for acceleration, you can have answers that are positive OR negative. What does a positive answer mean? What does a negative answer mean?
- You are going to your hometown by a bus that is moving with acceleration. During the journey, if you toss a coin, will it fall to the same spot? If no/yes, ExplainAn object is moving in such a way that the velocity is changing (only direction is changing, but magnitude is same) all the time. Is it possible to get acceleration from that motion? If yes, give an example. .A rock is rolled in the sand. It starts at 5.0 m/s, moves in a straight line for a distance of 3.0 m, and then stops. What is the magnitude of the average acceleration?
