A car starts from rest and accelerates at 2m/s² for 30 seconds. He then travel and constant speed for 1 minute and finally decelerates at 4m/s². Find max speed,
Total distance covered?

answer: hey stupid

what the hell you doing i need you at my house

explanation: it's me king omoregie

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.
