Question

an object of mass 100 kg is accelerated uniformly from velocity of 5m/s to 8m/s in 6sec calculate initial and final momentum. also calculate the acceleration of the object​

Answer 1

m = 100kg

U = 5m/s

V = 8m/s

t = 6sec

Initial momentum = mu

= 100*5

= 500kg m/s

Final momentum = mv

= 100*8

= 800kg m/s

A = v-u/t

= 8-5/2

= 3/2 m/s^2

Now, F = ma

= 100*3/2

= 150N

Answer 2

$\huge\boxed{Hey\: Mate}$

Answer:

mass of the object = 100 kg.

time taken = 6 sec.

initial velocity = 5 m/s.

final velocity = 8 m/s.

initial momentum of the object = 100*5=500 kg.m/s.

final momentum of the object =  100*8=800 kg.m/s.

force required = rate of change of momentum / time taken.

force=(800 - 500) / 6

force=300/6

force= 50 N.

 i hope that thus will help u.....
