Question

a body having initial velocity zero is moving with uniform acceleration of 8 metre per second square the distance travelled by it in its fifth second is

Answer 1

Here
u = 0
a=8m/s²
t=5secs
S(distance)=?
S=0+1/2*8*(5)²
=4*25
=100meters

Answer 2

Here

u = 0

a=8m/s²

t=5secs

S(distance)=?

S=0+1/2*8*(5)²

=4*25

=100meters
