Question

A car starting from rest traveling along the straight line attains a velocity of 20 m/s in 40 sec. find the acceleration and the distance travelled by the train for attaining this velocity.

Answer 1

ANSWER

let initial distance traveled by the car is s1, in time t1, and velocity is v1 then

s1=21αt12

v1=αt1

v12=2αs1

let remaining distance traveled by the car is s2
