Question

why a body of mass 100 kg is accelerated uniformly from a velocity of 5 metre per second to 10 metre per second in 5 seconds calculate A) initial momentum of the body B) final Momentum and C) the force acting on the body​

Answer 1

Answer:

Here is your ans mate

Explanation:

i) Initial momentum

momentum = p

mass = m = 100kg

velocity(initial) = u = 5

So,

p= mv

p = 100× 5

p = 500

ii) Final momentum

Same,

p=mv

p = 100 × 10

p = 1000

iii) Force acting

Here,

acceleration = v-u/t

= 10-5/5

= 5/5

= 1m/s²

And,

Force = mass × acceleration

F = ma

F = 100 × 1

F = 100N
