Question

two shopping carts are being pushed through a parking lot. the kinetic energy of each shopping cart depends on the shopping carts mass and speed. compare the two shopping carts. the full carts mass is the empty carts mass. the full carts speed is the empty carts speed. the full carts kinetic energy is the empty carts kinetic energy.

Explanation:

Step1: Compare the masses

The mass of the full cart is \(60\) kg and the mass of the empty cart is \(20\) kg. Since \(60>20\), the full cart's mass is greater than the empty cart's mass.

Step2: Compare the speeds

The speed of the full cart is \(10\) dm/s and the speed of the empty cart is \(10\) dm/s. Since \(10 = 10\), the full cart's speed is equal to the empty cart's speed.

Step3: Compare the kinetic energies

The kinetic energy of the full cart is \(30\) J and the kinetic energy of the empty cart is \(10\) J. Since \(30>10\), the full cart's kinetic energy is greater than the empty cart's kinetic energy.

Answer:

The full cart's mass is greater than the empty cart's mass. The full cart's speed is equal to the empty cart's speed. The full cart's kinetic energy is greater than the empty cart's kinetic energy.
