Question

Racing car has a uniform acceleration of 10 metre per second square. What distance it wil cover in 30 secs after starting from rest

Answer 1

Using equation of motion:-

s=ut+1/2at²

u=0

t=30

a=10

Solution:-

s=(0)(30)+1/2(10)(30)²

s=0+(5)(900)

s=4500m

Ans.=Racing Car will cover 4500 m

Answer 2

s = at² / 2   [u = 0]

s = 10 × 30² / 2

s = 4500 m
