Sam, whose mass is 75 kg, straps on his skis and starts down a 50-m-high, 20 frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Use work and energy to find Sam's speed at the bottom.

What is an aerodynamic shape? What is the definition?

Old cannons were built on wheeled carts, both to facilitate moving the canon and to allow the canon to recoil when fired. When a 200 kg canon in car recoils at 1.7 m/s, at what velocity would a 10 kg cannonball leave the Cannon?
