How many times will the impulse of the ball change if its mass becomes three times greater, and the speed is two times less?
| December 7, 2020 | education
Body impulse p:
p = mv, where m is the mass of the body, v is its speed.
Let the initial impulse of the ball be p1:
p1 = mv.
When the mass and speed changed:
p2 = 3m × v / 2 = 3p1 / 2.
Answer: the momentum of the ball will increase 1.5 times.
