Problem B2. A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill from a height h = 2.00 m to the base, where it meets a %3D rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. %3D h M Figure B2. Problem diagram B2 a) Find the speed with which the box reaches the base of the hill.

Two blocks with masses m1 = 5 kg and m2 = 15 kg are connected by a rope as shown. Thehorizontal surface is smooth and the pulley is weightless and frictionless. If the block starts fromrest, what is the speed of m2 after it has fallen by 6 m. Ans. 9.40 m/s
Gayle runs at a speed of 3.20 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is med ocum 15.0 m? Gayle's mass is 49.5 kg, the sled has a mass of 5.45 kg and her brother has a mass of 30.0 kg. m/s Need Help? Read It gy

An empty coal car is moving at a certain speed along a level frictionless track. (a) It begins to rain and the cart collects some rainwater. What happens to the speed of the car? (b) The rain stops and the collected rainwater leaks out from the car. What happens to the speed of the car now? Explain your answers briefly.
A shooting star is actually the track of a meteor, typically a small chunk of debris from a comet that has entered the earth’s atmosphere. As the drag force slows the meteor down, its kinetic energy is converted to thermal energy, leaving a glowing trail across the sky. A typical meteor has a surprisingly small mass, but what it lacks in size it makes up for in speed. Assume that a meteor has a mass of 1.5 g and is moving at an impressive 50 km/s, both typical values. What power is generated if the meteor slows down over a typical 2.1 s? Can you see how this tiny object can make a glowing trail that can be seen hundreds of kilometers away?
6. Your friend (mass 65.0 kg) is standing on the ice in the middle of a frozen pond. There is very little friction between her feet and the ice, so she is unable to walk. Fortunately, a light rope is tied around her waist and you stand on the bank holding the other end. You pull the rope for 3.00 s and accelerate your friend from rest to a speed of 6.00 m/s while you remain at rest. What is the average power supplied by the force you applied?
A 5 kg block falls from rest down a 7 m high frictionless hill. It collides with a stationary 2 kg block at the bottom of the hill. The two stick together and move 0.1 m along a level surface with coefficient of kinetic friction ug = 0.005. They then fall down another frictionless hill of height 2m. How fast are they moving at the bottom of this hill?
A 1.91 kg mass is initially at rest upon a frictionless, horizontal surface. An applied force of 8.2 N i then acts on the mass for 3.97 seconds. What is the speed of the mass when the applied force stops acting?
