What is the mass of the cannon? Mass cannonball = 5Kg

Velocity of the fired cannonball = 90m/s

Velocity of the cannon = -2.25m/s

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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.
