Determine the object with a higher kinetic energy: a) a snowmobile with a mass of 227.8 kg moving at 67 m/s or b) a truck with a mass of 15000 kg moving at 28 km/h.

Initially, two positively charged particles are brought together, and then they are released. When the particles are released, repulsion between them leads them to migrate apart. Does the distance between the two particles affect the potential energy of the particles before their release?

Imagine you have two blocks of metals, one is composed of iron and the other is composed of platinum. When both blocks are released from a height at the same, they will have the same velocity as they hit the ground. Will they also have equal kinetic energies?

A 1500 kg car is moving at a speed of 115 m/s. What is its kinetic energy?

A 150-g baseball was thrown upward. At the apex of the throw, the ball is 31.0 m above the ground. Calculate the potential energy of the ball at the apex of the throw.
