Estimate the buoyant force exerted on your body by the air ( use Pair+1.029 kg/m^3). What would be the difference between your weight in the air and your weight in a vacuum? How would I proceed with this? What Equation should I use?

Homework Statement A 1 Kilogram object with speed of 2.0 m/s in the positive x direction has a head -on elastic collision with a stationary 0.70Kg object located at x=0. What acceleration does the stationary object experiences during the collision if the collision occurs over 0.2 seconds...

Why a ball remains staionary when placed on a perfectly level surface? It is because of an objects natural state is to remain "at rest" and due to friction? Also due to no forces acting on it on left or right side (-x, x) direction? What equation would one use to prove this?

That is the whole problem. Where do I go next then or what is the right equation?

Homework Statement Question Details: 9. Problem: A stone is thrown verticall upward with a speed of 12.0 m/s from the edge of a cliff 70.0m high. How much later does it reach the bottom of the cliff? What is its speed just before hitting the ground? What total distance did it travel...
