Question

The car travelles a distance of 100 m with constant acceleration and average velocity of 20 m s^-1 the final velocity aquiered by car is 25 m s ^-1 find the initial velocity and acceleration of car

Answer 1

Explanation:

average velocity= v+u/2

u= 2 av - v

u = 2×20-25

= 15 m/s

also av= displacement/ time

t= d/ v

= 100/20

=5 s

now finally we can get a= v-u/t

= 25-15/5

= 10/5

=2 m/s2
