Question

find the momentum of a body of mass 100kg with a uniform velocity of 2m/s​

Answer 1

Answer:

Momentum is the product of mass and velocity shop the momentum will be 200 kilogram metre per second

Answer 2

Answer:

ANSWER

Initial velocity u=5m/s

final velocity v=8m/s

time =6s

mass =100kg

We know that Momentum =velocity×mass

So, Initial Momentum =initialvelocity×mass=5×100=500kgm/s

Final Momentum =Finalvelocity×mass=8×100=800kgm/s

Also, Force =mass×acceleration

by newtons first law of equation,

v=u+at

⇒a=

t

v−u

=

6

8−5

=0.5m/s

2

So, Force =mass×acceleration=100×0.5=50N
