A horse while running at a constant velocity of 15 ms−1m{s^{^{^{ - 1}}}} develops momentum of 3000 Ns. The mass of horse is
A. 180 kg
B. 300 kg
C. 200 kg
D. 250 kg

Explanation

Solution

In order to solve this question we should know the momentum formula, the wheel is running with a velocity and its having some mass it contains the property called momentum.

Complete step by step answer:
Given V=15ms−1m{s^{^{^{ - 1}}}}
P=3000Ns
Momentum = mass × velocity
M=PV\dfrac{P}{V}
= 3000/15
=200 kg

Hence the correct option is C.

Additional information: The total momentum cannot be created or destroyed when the two or more bodies in an isolated system collide each other. Hence the total momentum is constant unless or until an external force is acting on it.

Note: Momentum can be defined as mass in motion. When any of the objects contains mass in it and it is moving with some velocity v then the object has the property of momentum. In other ways, if an object has some momentum then the object which is dependent upon two variables is given as mass and velocity.
