- Bank robbers have pushed a 1000 kg safe to a third-story floor-toceiling window. They plan to break the window and lower the safe 10.0 m to their truck. Not being too clever, they stack up 500 kg of furniture, tie a rope between the safe and the furniture, and place the rope over a pulley. Then they push the safe out of the window. The coefficient of kinetic friction between the furniture and the floor is 0.5. The rope would break if the force on it exceeds 5000 N. a) Does the rope break? b) What is the acceleration of the safe? c) What is the safe’s speed when it hits the truck?It was a snow day, so Eric and some friends went sledding. He boarded his 60-inch sled and descended the steepest section near the tall trees. Before his ride ended at the location of a tree stump buried a few inches below the snow, he was accelerating at 2.41 m/s/s down the 20.1° incline. Determine the coefficient of friction between the sled and the snow. (Coefficients of friction are positive, so use the absolute value of your answer.) Use the approximation g ≈ 10 m/s2.A 91 kg janitor wearing running shoes is running across an ice rink at a speed of 3.2 m/s. They try to stop abruptly, but keep sliding across the surface of the ice. The ice exerts a frictional force of 13.4 N to slow them down. How far do they travel before halting to a stop?
- A hockey puck with mass 0.166 kg is pushed across the ice with a constant force of 0.89 N. The coefficient of kinetic friction between the puck and the ice is 0.22. After a distance of 2.6 m, what is the puck's speed in m/s?A 200 g hockey puck is launched up a metal ramp that is inclined at a 30° angle. The coefficients of static and kinetic friction between the hockey puck and the metal ramp are μs = 0.40 and μk = 0.30, respectively. The puck's initial speed is 50 m/s. What vertical height does the puck reach above its starting point?sadasdasdasdas
- A 20-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 28 N. Starting from rest, the sled attains a speed of 2.6 m/s in 9.4 m. Find the coefficient of kinetic friction between the runners of the sled and the snow.A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.A 0.19 kg hockey puck slides across an icy surface and experiences a small friction force of 0.09 N. If the puck is given an initial velocity of 4m / s how far does it slide before stopping? Your answer should be in units of m but you should only submit the number for your answer.
- Tom reached a speed of 29 m/s in the downhill skiing competition. Suppose he left the slope at that speed and then slid freely along a horizontal surface. If the coefficient of kinetic friction between his feet and the ground was 0.27 and his final speed was half of his initial speed, find the distance he traveled?The 60-kg crate is projected along the floor with an initial speed of vo = 6.8 m/s at x = 0. The coefficient of kinetic friction is μk = 0.55. Calculate the time t required for the crate to come to rest and the corresponding distance x traveled. Answers: t = Hk X = i VO S mA student pushes a physics textbook of mass 1.15 kg across a table with a horizontal force of 5.48 Newtons. If the frictional force between the table and the textbook is 3.38 Newtons and the textbook was initially at rest, what is the speed of the textbook after 2.3 seconds? Remember to give your answer in metres per second and to at least 3 significant figures.
