Question

A car starting from rest attains a velocity of 20 m/s in 10 second assuming that the acceleration is uniform find the distance travelled by the car attending the velocity

Answer 1

Answer:

100 m

Step-by-step explanation:

let the distance travelled in 10 s = s

final velocity ,v = 20 m/s

initial velocity , u = 0 m/s

time taken ,t = 10 s

acceleration ,a = (v-u)/t

(20 - 0)/10 = 2 m/s^2

therefore ,

v^2 - u^2 = 2as

s = (v^2 - u^2 )/2a

s = (20^2 - 0)/2 *2

s = 400/4 = 100 m
