How does kinetic energy work in braking a vehicle?

網頁In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if when applied it has a component in ... 網頁The correct answer is d) 8 m/s^2. The formula for kinetic energy is KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity.
