Question 8

A sprinting cheetah with a mass of 45 kg is running across the savanna. At its peak speed, the cheetah has 12 960 J12\ 960\text{ J}12 960 J of kinetic energy.

Calculate the velocity of the cheetah.

Use the equation:

kinetic energy=0.5×mass×velocity2 \text{kinetic energy} = 0.5 \times \text{mass} \times \text{velocity}^2 kinetic energy=0.5×mass×velocity2
