Aplacekicker kicks a football upward at an angle of 30 and a speed of 5.0 m/s at what other angle will he have to kick a second ball with the same speed to reach the same distance downrange ignore air resistance

60

90

45

15

Explanation:

Given

speed of ball

launch angle

Range of a Projectile

Range will be common for two angles i.e.

for

For

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.
