A baseball is hit at ground level with a velocity of 46m/s at an angle of 30° with the horizontal. The ball lands at ground level on the other side of the fence. (Fortunately, Kyle was not pitching).
a) How long is the ball in the air?
b) How high does the ball go?
c) How far did the ball land from its starting point?

less than one you can't create energy

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.
