If the graph shown is a position-time graph of an object moving at constant velocity, what is the velocity of the object? Assume that the units of position are meters and the units of time are seconds. A) 0.02 m/s B) 10 m/s C) 50 m/s D) 75 m/s

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

Which of the following are appropriate acceleration units?
