You throw a softball (of mass .350 kg) straight

up into the air. It reaches amaximum altitude

of 5.8 m and then returns to you.

What is the gravitational potential energy

of the softball at its highest position? Assume

the ball departed fromand returned to ground

level. Answer in units of J.

003 (part 2 of 4)

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.

004 (part 3 of 4)

What is the kinetic energy of the softball when

it returns to your hand? Answer in units of

J.

005 (part 4 of 4)

What is the speed of the ball? Answer in

units of m/s.

**2. Relevant equations**

PE=massxgravityxdisplacement

KE=1/2xmassxvelocity(squared)

TE=PE+KE

**3. The attempt at a solution**

I solved for the first problem getting 19.894 Joules, but I ma having trouble solving for the second part. I can't seem to find the total energy.
