According to the Law of Conservation of Energy, a golf ball with 100 Joules of gravitational potential energy at its maximum height will have how many Joules of kinetic energy right before it hits the sand when it is dropped?

#"100 J"#

Explanation:

#"Total energy = Kinetic energy + Potential energy"#

At maximum height there is no kinetic energy because it’s at rest

#"T.E"_i = "Potential energy = 100 J"#

When it hits the ground potential energy is zero because #h = 0#

#"T.E"_f = "Kinetic energy"#

According to law of conservation of energy

#"T.E"_f = "T.E"_i#

#"K.E = 100 J"#
