A baseball is struck by a bat and 3 s later it is caught 30 m away. 3) A baseball is struck by a bat and 3 s later it is caught 30 m away.
a) If the baseball was 1 m above the ground when it was struck and caught, what was the greatest height it reached above the ground?
b) What were the horizontal and vertical components of its velocity when it was struck?
c) What was its speed when it was caught?
d) At what angle with the horizontal did it leave the bat?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
