Question

a ball rolls down a ramp for for 15 seconds if the initial velocity of the ball was 0.8 seconds and the final velocity was 7 metre per second what was the acceleration of the ball​

Answer 1

Answer:

0.41 m/s^2

Explanation:

let me tell you how.

we were asked to find the acceleration of a ball as it rolls down a ramp given initial velocity and the final velocities , the time interval.

to do this,

v=v+at

where,

v= final velocity that is 7m/s

vox= intial velocity 0.8m/s

t= 15s

plugging in those values we have,

7m/s= 0.8m/s+ax(15s)

ax= 7m/s- 0.8m/s divided by15s so we get

0.41m/s^2

over and happy to help! :)
