5. A body of mass 25 kg has a momentum of 125 kg m/s. Calculate the velocity of the body
Answers
Answer:
5
Explanation:
momentum=m.v
125=25×v
v=5m/s
Answer:
Hence, the velocity of the body = 5 m/s
Explanation:
Given,
Mass of the body, m = 25 Kg
Momentum of the body, p = 125 Kg m/s
Let the velocity of the body be 'v'. Then, we know that,
Momentum = mass × velocity
=> p = mv
=> 125 Kg m/s = 25 Kg × v
=> v = (125 Kg m/s) / (25 Kg)
=> v = 5 m/s
Hence, the velocity of the body = 5 m/s
'A piece of Supplementary Counsel' :-
• Momentum = In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
• Velocity = The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.
• Mass = Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.
