1. How much kinetic energy does an object of mass m traveling with a velocity vx in the x-direction have? 2. How much kinetic energy does an object of mass m traveling with a velocity ~v = vx ˆi + vy ˆj have? 3. Since the pythagorean theorem states that v ^2 = v ^2 x + v ^2 y , we can write the kinetic energy as K = 1/2mv^2 x + 1/2mv^2 y . Does this mean that...

4. Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1? Convert your answer to megatons of TNT (1 megaton of TNT = 4.18 x 1015 joules).

When the driver applies the brakes of a light truck traveling 40 km/h, it skids 3m before stopping. How far will the truck skid if it is traveling 80 km/h when the brakes are applied? Solve using kinetics. Do not use work and energy principles.
