Two rail cars roll without friction on a track. The rail cars have different masses. The heavier car is at rest. The lighter car is moving with speed v, hits the heavier car, and sticks to it. The combined two-car system then moves with speed v/5. What is the ratio of masses of the two cars? Ratio = mass of heavier car / mass of lighter car.
A 719-N man stands in the middle of a frozen pond of radius 4.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2-kg physics textbook horizontally toward the north shore at a speed of 4.0 m/s. How long does it take him to reach the south shore?
A 5.8-kg toboggan is kicked on a frozen pond, such that it acquires a speed of 2.1 m/s to the right. The coefficient of friction between the pond and the toboggan is 0.18. Determine the distance that the toboggan slides before coming to rest. Answer: m (round to the nearest hundredth)
Two blocks with masses Mj and M2 are connected by a massless string that passes over a massless pulley as shown. M has a mass of 2.25 kg and is on an incline of 0 41.5° with coefficient of kinetic friction u = 0.205. M2 has a mass of 5.25 kg and is on an incline of 02 = 34.5° with coefficient M2 of kinetic friction u, = 0.105. The two-block system is in M1 motion with the block of mass M2 sliding down the ramp. Find the magnitude az of the acceleration of M, down the incline. Figure is not to scale. a2 = m/s?
Lizzy is training on the trapeze when a slight accident occurs. As a result, she is now hanging from the middle of a 60 m safety rope connected to the ceiling on one end and held by a strongwoman from the circus on the other end. She has a mass of 50 kg and the part of the rope connected to the ceiling makes an angle of 55° with the vertical. The part of the rope that connects Lizzy to her fellow circus artist makes an angle of 20° above the horizontal (the strongwoman is above Lizzy). As long as Lizzy remains stationary, what is the tension in both parts of the rope?
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 have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid castward with their wheels locked for 18.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. What speed (in miles per hour) was car A traveling just before the collision?

A train of mass 9.26e+4 moving with a velocity of magnitude 72.9 hits a car of mass 1.78e+3 at rest. If the train exerts a force of magnitude 1.86e+3 on the car, what is the magnitude of the force exerted by the car on the train? All quantities are given in Sl units and the answer should be given as a positive or negative number in SI units. Only type a number into the answer box, do not type in units.

Mary and her sister are playing with a cardboard box on the neighborhood hill. Mary climbs into the box, the total mass of the box with Mary in it is 115 kg. The box starts at rest at the beginning of the incline. The hill is at an incline of 28 degrees with respect to the horizontal.The static and kinectic friction between the box and hill is 0.4 and 0.2 respectively. Assume that Mary is now in the box, but has not started to move. a. What is the magnitude of the friction force acting on the box?b. What is the magnitude of the net force acting on the box and child system?c. Will the box slide down the hill, or stay at rest?
Multiple-object systems with friction: Two boxes are connected by a weightless cord running over a very light frictionless pulley as shown in the figure. Box A, of mass 8.0 kg, is initially at rest on the top of the table. The coefficient of kinetic friction between box A and the table is 0.10. Box B has a mass of 15.0 kg, and the system begins to move just after it is released. A B (a) Draw the free-body diagrams for each of the boxes, identifying all of the forces acting on each one.
