What is faster, up or down? A ball of dough ?? = 1 kg is thrown vertically upwards from the surface of the Earth, with a positive initial velocity ??0 = 20 m / s. Suppose the forces acting on the ball are gravity and a retarder of air resistance, with opposite direction to that of the movement. 2._ If the retarding force is proportional to the instantaneous velocity, use the second law of Newton to determine an equation that...

A zero-friction (air bearing) cart is heading downhill on a slightly inclined track. At a moment when the cart’s speed downhill is 2.15 m/s, a fan thruster on the cart is activated. The cart immediately begins to experience constant acceleration, such that is slows in its motion, stops for an instant (1.86 s after the fan is turned on), and begins to drive uphill. Analyze the motion beginning when the fan is turned on. How far does the cart travel...
