Two particles P and Q are shot vertically upwards. Particle P is first shot up with a velocity of 40m/s. After 4s, Particle Q is also shot up. Find: a)Where the two particles meet, If at the point of meeting, P has a velocity of 15m/s. b)The velocity with which Q is shot up.(g= 10m/s)

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.
