Answer:
Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.
Explanation:
Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;
momentum (P) = mass × velocity
i.e P = m × v
= mv
It is measured in Kgm/s.
The change in momentum of a body is referred to as its impulse (Ft).
ΔP = m(v - u) = Ft
Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
3 - b) weight decreases
4 -a) 50 kg as mass is same everywhere
5 - b) 200 dynes
