What is the momentum of a 48.2N bowling ball with a velocity of 7.13m/s?
Vesna [10]

Answer:

Momentum, p = 34.937 kg-m/s

Explanation:

It is given that,

Force acting on the bowling ball, F = 48.2 N

Velocity of bowling ball, v = 7.13 m/s

We have to find the momentum of the ball. Momentum is given by :

p = mv........(1)

Firstly, calculating the mass of bowling ball using second law of motion. The force acting on the ball is gravitational force and it is given by :

F = m g    (a = g)

m=\dfrac{F}{g}

m=\dfrac{48.2\ N}{9.8\ m/s^2}

m = 4.9 kg

Now putting the value of m in equation (1) as :

p=4.9\ kg\times 7.13\ m/s

p = 34.937 kg-m/s

Hence, this is the required solution.
