Question

A body moving with a velocity of 6 m/s uniform accelerates at 1.5 m/s2
. What is the
velocity after 5 sec. and how for will it move in the time.

Answer 1

Answer:

GIVEN-

u=6 m/s

t=5s

a=1.5 m/s^2

v=?

v=u+at

v=6+7.5=13.5 m/s

Now,s=ut+1/2at^2

s=30+3.75

s=33.75 m/s.

Answer 2

u is given i.e.6m/s

a is given 1.5

and t is given 5 sec

Explanation:

Thus we will use the 1st eq. of motion i.e.

v=u+at

We put the given values

v=6+1.5*5

v=6+7.5

v=13.5m/s

Thus the final velocity is 13.5 m/s.
