Answer :
The kinetic energy of the shopping cart is 3,343.26 Joules. This value represents the energy associated with the cart's motion, determined by its mass and velocity.
The formula for kinetic energy takes into account both factors, with the mass contributing to the magnitude of the energy and the velocity squared amplifying it further. In this case, the shopping cart's mass of 84 kg and velocity of 9.3 m/s result in a substantial amount of kinetic energy. This energy is important to consider for various reasons, such as understanding the forces involved in pushing and stopping the cart and evaluating potential risks or impacts associated with its motion.

The kinetic energy of an 84 kg shopping cart moving at 9.3 m/s is 3628.62 J.
To calculate the kinetic energy of the shopping cart, we use the formula for kinetic energy, which is KE = (1/2)mv^2, where m is the mass of the object and v is the velocity.
For an 84 kg shopping cart moving at a speed of 9.3 m/s, the kinetic energy would be:
KE = (1/2) x 84 kg x (9.3 m/s)^2 = 3628.62 Joules.
Therefore, the shopping cart has 3628.62 J of kinetic energy.
