Question

A ball on a ramp starts from rest and has an acceleration of 0.268 m/s². 1. Find the displacement after 1 second. 2. Find the displacement after 4 seconds. 3. Find the final velocity after 1 second. 4. Find the final velocity after 4 seconds.​

Answer 1

1)the displacement of 1 second is

s=0.134 m

2)the displacement after 4 seconds is

s=2.1444 m

3)the volocity after 1 second is

v=0.268 m/s

4)the volocity after 4 seconds is

v=1.072 m/s
