Explanation:

to calculate the magnitude of the velocity at any point in time, multiply the constant acceleration rate times the time difference and then add it to the initial velocity. As an example, if you dropped a rock off a cliff, its velocity increases by 32 feet per second, every second.

Explanation:

For potential energy in joules the formula is

PE= mgh

In which m is the mass in kg, g is the gravitational force 9.8 m/sec^{2} , and h is the height above the ground.

PE= 5*9.8*10=490

We round 490 to 500

Explanation:

PE=mgh; mg = F (Gravity)

PE= (37 N) (3m)

PE = 111 J
