Question

A racing car has a uniform acceleration of 4cm/s-2. What distance will it cover in 10sec after start?

Answer 1

a=4cm/s^-2
t=10 sec.

initial velocity be 0
then

s=ut+1/2at^2
s=0+1/2 ×4 ×100
200 cm=2m

so car will cover 2m in 10 sec.

hope this will help you.

Answer 2

a=4cm/s -2,u=0(uniform)
t=10sec
s=??
s=u+1/2at2
s=1/2.4.10×10
s=200cm
