A ball starts from rest. It rolls down a ramp and reaches the ground after 4 seconds. Its final velocity when it reaches the ground is 7. 0 meters/second. The initial velocity of the ball is meters/second, and its acceleration is meters/second2.

Respuesta :

Answer:

initial velocity: 0.0 m/s, acceleration is 1.75 m/s/s or m/s^2

Explanation:

Ball begins at rest; change in velocity/change in time (7-0/4-0) is acceleration
