A car accelerates uniformly from 10 ms-to 20 ms- as it travels 500 m along a straight road.
(a) Find the acceleration of the car.
(b) Find the time taken by the car to travel the 500 m.

newton's first law of motion

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

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.
