Question

10)A car is moving from rest and attained a velocity of 80 m/s. Calculate the
acceleration of the car after 5 s?

Answer 1

Explanation:

the velocity graph of a ball mass 20mg moving along a straight line

Answer 2

16m/s^2

Explanation:

initial velocity (u) =0

final velocity (v) =80

acceleration =?

Now,

acceleration = (v-u)/t

=(80-0)/5

= 80/5

= 16m /s^2
