Question

a car travels a distance 100m with a constant acceleration and average velocity is 20m/s the final velocity acquired by the car is 25m/s find (I) initial velocity and (ii) acceleration of car

Answer 1

hey there,,,,,,

given:: s= 100m,,

V(av)= 20m/s

V(final)= 25m/s..

we know that average velocity

V(av)= V(final)+ V(initial)/2

20= 25+V/2

25+V= 40

V(initial)=15m/s

(ii) v^2- u^2= 2as

(25)^2- (15)^2= 2×100×a

625- 225= 200a

a= 400/200

a= 2m/s...

hope it is clear❕❕
