A child sits on the edge of a spinning merry-go-round that has a radius of 2.6 m. The child's speed is 3 m/s. What is the child's acceleration?

A ball, rolling with velocity 3 m/s, rolls off a cliff. The cliff ledge is 70 m above the ground below. What is the horizontal distance the ball will travel before hitting the ground. Give the answer in meters.

Q4. A stone was dropped from a cliff of height 100 m. Ignoring air resistance, how long will it take the stone to reach ground? juaiļ, o ú 49 49 =4 t -4.9t Q5. A stone was dropped from a cliff of height 100 m. Ignoring air resistance, what will be the final speed of the stone when it reaches ground? Q6. An object has an initial velocity of 8 m/s and acceleration of 2 m/s?, how far the object will move in 10 seconds?

You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?

A golfball rolls off a 0.8 m high desk and strikes the floor 0.4 m away from the base of the desk. How fast was the ball rolling?

2. You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. you drop a ball from a height of 1.22 m above the floor. The ball hits the floor 0.349 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     20.0 m/s^2     10.0 m/s^2     15.0 m/s^2     30.0 m/s^2

You are diving board over a swimming pool. You are throwing upward a tennis ball at a speed 3 m/s. On its way back down the tennis ball narrowly misses the diving and hits the water below at 15 m/s. The board is about

A rock is thrown straight downward near the Earth’s surface with initial velocity of 20m/s down.  Assuming it doesn’t reach the ground, after 4 seconds its speed will be about

A ball, rolling with velocity 2 m/s, rolls off a cliff. The cliff ledge is 90 m above the ground below. What is the horizontal distance the ball will travel before hitting the ground. Give numerical answer in meters.
