A ball rolls along a desktop with an uniform velocity of 3 m/s. What is the displacement after 10 seconds have passed?

A ball is thrown upward with an initial velocity of 18 m/s? What is the maximum height the ball reaches if the ball is assumed to leave from the ground?

A ball is dropped from a 35 m tall building. The ball takes how long to impact the ground?

first part the answer is 30 m. d= rt so distance = rate (3) times the time (10) so the distance is 30
