Suppose a car has 4000 J of kinetic energy. What will be its kinetic energy if the speed is doubled? What if the speed is tripled?

Text Solution

AI Generated Solution

To solve the problem, we need to understand the relationship between kinetic energy and speed. The formula for kinetic energy (KE) is given by: \[ KE = \frac{1}{2} m v^2 \] where: - \( KE \) is the kinetic energy, ...
