Question

4. A racing car has a uniform acceleration of 4 m s - '2. What distance will it cover in 10 s after start?

Answer 1

Answer:

200 m

Explanation:

Initial velocity- 0

final velocity= v

time= 10 seconds

to find final velocity

v= u + at

v= 0 + 4*10

v= 0 + 40

v= 40 m/s

to find distance

s= ut + 1/2at²

s= 0*10 + 1/2*4*(10)²

s= 1/2 *4*100

s=200m

answer : 200 m
