A body of mass 5 kg at rest is acted upon by a force.its velocity changes to 10 ms.find its initial and final momentum
Answers
Answer:
Given:
An object is at rest, it is acted upon by a force , it gains a velocity of 10 m/s.
Mass = 5 kg
initial velocity = 0 m/s
final velocity = 10 m/s.
To find:
Initial and final momentum
Concept:
Momentum is actually the index of inertia of a body. It gives us an idea of the movement of the body with respect to its mass and velocity.
Mathematically it is the product of mass and velocity.
Formulas used:
Momentum = mass × velocity
Let momentum be denoted as "P"
Calculation:
Initial momentum = P1 = m × V1
=> P1 = 5 × 0
=> P1 = (0) kg m/s
Final momentum = P2 = m × V2
=> P2 = 5 × 10
=> P2 = 50 kg m/s
Answer:
Explanation:
Given :-
Mass of body = 5 kg
Initial velocity of body = 0 m/s
Final velocity of body = 10 m/s
To Find :-
Initial and Final momentum
Formula to be used :-
Momentum = mass × velocity
Solution :-
Putting all the value, we get
⇒ Initial momentum = m × V₁
⇒ Initial momentum = 5 × 0
⇒ Initial momentum = 0 kg m/s
⇒ Final momentum = m × V₂
⇒ Final momentum = 5 × 10
⇒ Final momentum = 50 kg m/s
