Question

when a missile is fired from a tanker gets momentum of 200 kg metre per second if the velocity of the Missile is 50 M per second what will be its mass

Answer 1

According to Newton's second law of motion
p=mv where p=momentum,m=mass and v=velocity.
So we have ----
200 kg m/s^2 = m* 50m/s
=> m = 200kg m/s / 50m/s
=> m = 4 kg

Answer 2

Momentum formula is as follows :

Momentum = Mass × Velocity

In our case the following has been given :

Momentum = 200 kgms⁻¹

Velocity = 50 m/s

Mass = Momentum / Velocity.

We do the substitution below as follows.

Let the mass be m then :

200 = 50m

m = 200/50 = 4

The mass of the missile = 4kg.
