The gravitational potential energy of the netball before shooting it into the net is 2.45 Joules.
The question asks for the gravitational potential energy of a netball when it is about to be shot into the net.
Gravitational potential energy is given by the formula P.E. = mgh, where m is the mass, g is the gravitational acceleration (approximately 9.8 m/s^2), and h is the height above a reference point.
In this case, the netball has a mass of 0.5 kg and is held 0.5 m above the player's head before shooting. Substituting the values into the formula, we get:
P.E. = (0.5 kg)(9.8 m/s^2)(0.5 m) = 2.45 J
Therefore, the gravitational potential energy of the netball when it is about to be shot into the net is 2.45 Joules.
The probable question may be:
A student who is 1.5 meters tall shoots a 0.03kg darkt out of a blow gun horizontally. what is the gravitational potential energy of the netball when it is about to be shot into the net?
