Question

5. A car has a uniform acceleration of 4m/s2 .What distance will it cover in 5 seconds after start?

Answer 1

acc.=4m/s^2

T=5sec

initial velocity(u)=0m/s

s=?

s=ut+at^2

s=0×5+4×5×5

s=4×25

s=100m

Answer 2

Given,

a = 4m/s^2

t = 5s

s = ?

u = 0

S= ut+1/2at^2
= 0×5+1/2×4×5×5
= 50

s = 50m

The distance covered in 5 s by the car is 50 m.
