You throw a softball (of mass 300 g) straight
up into the air. It reaches a maximum altitude
of 10.1 m and then returns to you.
What is the gravitational potential energy
of the softball at its highest position? Assume
the ball departed from and returned to ground
level.
Answer in units of J
29.69J ---^

Assume no energy is lost by the softball while
it is in the air.
What is the kinetic energy of the softball as
soon as it leaves your hand?
Answer in units of J
