If the 45-g ball acquires a speed of 67 m/s, estimate the magnitude of the force exerted by the club on the ball.

The magnitude of the force exerted by the club on the ball is 3015 N.

Explanation:

Given that,

Mass of the ball, m = 45 g = 0.045 kg

Speed acquired by the ball, v = 67 m/s

It is assumed that the club is in contact with the ball for about 0.0010 s.

To find,

The magnitude of the force exerted by the club on the ball.

Solution,

Initial speed of the ball is 0, as it is at rest.

The force acting on the ball is given by second law of motion as :

F = 3015 N

So, the magnitude of the force exerted by the club on the ball is 3015 N.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
