Question

A car starts from rest and accelerates uniformly at 2m/s^2 for 10 secs.Find the velocity and the displacement at the end of 10 secs

Answer 1

Well...Lets see the given data:
u=0
t=10secs
a=2ms^2

By First equation of motion:
v=u+at
v= 0+2*10
v=20 ms^-1

S=ut+1/2at^2
S= 1/2*2*100
S=100m
Therefore, v=20ms^-1
and S= 100m

Thanks!!
