Question

A truck starts from rest and moves with constant acceleration. If it covers 200 m in first 10 seconds then find the distance(in m ) it will cover in next 5 seconds​

Answer 1

in 10second a truck covers 200m

in 1 second a truck covers 200/10

in 5 second a truck covers 200 /10*5

answer is 300m

Answer 2

Dear Student,

◆ Answer -

50 m

● Explanation -

Acceleration is calculated by -

s = ut + 1/2 at^2

200 = 0 × 10 + 1/2 × a × 10^2

200 = 0 + 50a

a = 200 / 50

a = 4 m/s^2

Distance covered in 5 s is given by -

s' = ut' + 1/2 at'^2

s' = 0 × 5 + 1/2 × 4 × 5^2

s' = 2 × 25

s' = 50 m

Hence, the truck covers 50 m in 5 s.

Thanks dear. Hope this helps you..
