A car starts from rest and accelerates at 5 m/s/s. a) what is the position of the car after 4 seconds?
b) what is the speed of the car after 4 seconds?
c) how long will it take the car to travel 100 meters?
d) how long will it take the car to reach 30 m/s?

see earlier answer

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.

mass:

formula.

example:

given values:

mass = 0.3 kg.

that would be because of both gravity and friction. so     c
