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.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
