Problem 1: A puck of mass m is held to a weight of mass M by a thin string of negligible mass. The puck is placed on top of a frictionless table, and the weight and string are sent through a hole in the table, as shown: It is possible to prevent the puck from also falling into the hole if we give it some initial speed v, at which it will move in a uniform circular motion about the hole at a radius r. What is the speed v that will keep this system in equilibrium, i.e. keep the weight at rest and the puck at its uniform circular motion?

A hammer of mass m = 0.455 kg is moving horizontally at a velocity of v = 4.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 1.2 cm into a board. What is the duration of the impact, assuming the acceleration is constant during this time period, in terms of the given variables? What was the average force exerted on the nail, in terms of the mass, initial velocity, and distance traveled? What was the average force, in newtons, exerted on the nail?
A hockey puck with mass 0.160kg is at rest at the origin on the horizontal, frictionless surfaceof the rink. At t = 0, a player applies a force of 0.250N to the puck parallel to the surface. Hecontinues to apply the force until t = 2.00s. What are the position and speed of the puck at t =2.00?
In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.
The drawing shows Robin Hood(mass = 77.0 kg) about to escape froma dangerous situation. With one hand,he is gripping the rope that holds up achandelier (mass = 195 kg). When hecuts the rope where it is tied to thefloor, the chandelier will fall, and hewill b. pulled up toward a balconyabove. Ignore the friction between therope and the beams over which itslides, and find (a) the accelerationwith which Robin is pulled upward and (b) thetension in the rope while Robin escapes.
Why is the following situation impossible? An astronaut, together with the equipment he carries, has a mass of 150 kg. He is taking a space walk outside his spacecraft, which is drifting through space with a constant velocity. The astronaut accidentally pushes against the spacecraft and begins moving away at 20.0 m/s, relative to the spacecraft, without a tether. To return, he takes equipment off his space suit and throws it in the direction away from the spacecraft. Because of his bulky space suit, he can throw equipment at a maximum speed of 5.00 m/s relative to himself. After throwing enough equipment, he starts moving back to the spacecraft and is able to grab onto it and climb inside.
At a time when mining asteroids has become feasible, astronauts have connected a line between their 3070-kg space tug and a 5580-kg asteroid. They pull on the asteroid with a force of 307 N. Initially the tug and the asteroid are at rest, 436 m apart. How much time does it take for the ship and the asteroid to meet?

you were told that the girl's mass was three-fourths that of the boy's mass. The boy has a velocity of v = 0.77 m/s to the left. What would be the girl's velocity in this case? (Consider the ice to be frictionless. Enter the magnitude only.)
A block with mass m1 = 4.00 kg and a ball with mass m2 = 7.00 kg are connected by a light string that passes over a massless, frictionless pulley, as shown in the figure below. The coefficient of kinetic friction between the block and the surface is 0.300. Find the acceleration of the two objects and the tension in the string. (b) Check the answer for the acceleration by using the system approach.
