- A block is sliding along a horizontal surface where the coefficient of kinetic friction is 0.5 between the two. If the block as initial velocity 15.0 m/s, how much time does it take for the block to come to rest?A contestant in a winter games event pulls a 47.0 kg block of ice across a frozen lake with a rope over his shoulder as shown in the figure. F 25° The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (a) Calculate the minimum force F (in N) he must exert to get the block moving. N (b) What is its acceleration (in m/s2) once it starts to move, if that force is maintained? m/s²A 140 kg wooden crate resting on a wood floor. The coefficients of stattic and kinetic friction here are μs =0.5 and μk=0.3. WHat maximum force, in newtons, can you exert horizontally on the crate without moving it? If you continue to extert this force once the crate starts to slip, what will its accelertation be in m/s2?
- In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?A 105-kg baseball player slides into second base. The coefficient of kinetic friction between the player and the ground is μk = 0.659. (a) What is the magnitude of the frictional force? (b) If the player comes to rest after 1.32 s, what is his initial speed?A large cube (mass = M) being accelerated across a horizontal frictionless surface by a horizontal force . A small cube (mass = m) is in contact with the front surface of the large cube and will slide downward unless is sufficiently large. The coefficient of static friction between the cubes is u. What is the smallest magnitude that F can have in order to keep the small cube from sliding downward?
- A 4 kg block is sliding down a vertical wall while being pushed by an external force as shown in the figure. What is the magnitude of the acceleration of the block (in m/s2) if the coefficient of kinetic friction between the wall and the block is uj, = 0.20 and the magnitude of the external force is 20 N? 4 kg 30 X 8.8Scenario: You pull on a 7.9 kg block with a rope exerting a 34 N tension force that is directed 16 degrees above horizontal. If you were to pull the tiniest bit harder, the block would move, but at this tension the block stays put. Question: What is the coefficient of static friction between the block and floor?
