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).

A truck is traveling at a constant speed of 56.6 km/h . Suddenly, the driver sees a deer 24.0 m away and slams on the brakes. If the truck hits the deer 2.40 s after the driver slams on the brakes, what was the speed of the truck, in km/h, when the deer was struck? Assume motion was at constant acceleration.
