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?

  • physics : HELP PLEASE - ,

    (a) A ball rolls along a desktop with an uniform velocity of 3 m/s. What is the displacement after 10 seconds have passed?
    D = V*t

    (b) A ball is thrown upward with an initial velocity of 18 m/s?
    Vo^2/2 = g H
    Solve for height, H

    (c) A ball is dropped from a 35 m tall building. The ball takes how long to impact the ground
    35 = (g/2) t^2
    Solve for time, t.
