49.An object accelerates from rest to a speed of 24 m/s over a distance of 56 m. What acceleration did it experience?

Initial velocity,u = 0 m/s

Final velocity,v = 24 m/s

Distance covered,s = 56 m

Calculate the acceleration ( a ) .

According to the third equation of motion,

★ Substituting the values in the third equation of motion:

i guess it’s a and b

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.
