Question

A ball weighting 100 gram is thrown vertically upward with a speed of 25 metre per second what will be the momentum of the highest point​?​

Answer 1

Given :

Mass of the ball = 100 g

Initial velocity of the ball = 25 m/s

To Find :

The momentum of the ball at heighest point

Solution :

Momentum is defined as the product of mass and velocity of body. Mathematically, P = mv (here P is momentum, m is mass and v is velocity).

We have;

m = 100 g = 0.1 kg

And velocity at the highest point will be zero. So, v = 0 m/s. Now, calculating Momentum of given ball;

➙ P = (0.1 kg)(0 m/s)

➙ P = 0 kgm/s

Hence, the Momentum of the given ball at the highest point is Zero.

Answer 2

Answer:

______________________________

This question says that there is a ball and it's weight or mass is 100 g it's thrown vertically upward with a speed of 25 m/s means it's initial velocity is 0 m/s .Now we have to find the momentum of the highest point.

✪ Mass of ball = 100 g = 0.1 kg

✪ Initial velocity = 25 m/s

✪ Velocity be 0 m/s

Note : The velocity is be 0m/s because the object or velocity is the highest point that time

✪ The momentum of the highest point.

✪ The momentum of the highest point = 0 kg m/s

❃ Formula to find momentum

❃ Momentum↝ P = mv

❖ Momentum as P

❖ Mass as m

❖ Final velocity as v

➥ P = mv

➥ P = 0.1 × 0

➥ P = 0 kg m/s

Henceforth, the momentum of the highest point is 0 kg m/s
