If a 100 kg go-cart is accelerated to a velocity of 30m/s from rest show much work has been done on the go-cart? What kind of energy is being created?

The energy that is being created is kinetic energy

Kinetic energy= 45,000 joules

Kinetic energy can be described as the energy that is gotten when a body  is in motion

mass= 100 kg

velocity= 30m/s

K.E= 1/2 × 100 × 30²

= 0.5 × 100 × 900

= 45,000

Hence the amount of work done is 45,000 joules

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
