Question: The 250-kg crate rests on the ground for which the coefficients of static and kinetic friction are μs = 0.5 and μk = 0.4, respectively. The winch delivers a horizontal towing force T to its cable at A which varies as shown in the graph. Originally the tension in the cable is zero Part A) Determine the speed of the crate when t = 3.9 s. Hint: First determine the force needed to begin moving the crate. Express your answer to three significant figures and include the appropriate units

Block A has a mass of 29 kg and block B has a mass of 41 kg. The two blocks are stacked on the ramp with an incline of 0 = 32.2°. Determine the largest horizontal force F that can be applied to block B without either block moving for each of the following two cases: a.) The friction coefficient for the contact between blocks A and B is Hs1 = 0.6 and the friction coefficient for the contact between block A and the ramp is Hs2 = 0.22. b.) The friction coefficient for the contact between blocks A and B is µs1 = 0.6 and the friction coefficient for the contact between block A and the ramp is Hs2 = 0.55. F A Part a) The limiting slip condition occurs at the contact between A and the ramp v The maximum force before either block A or B slips is N Part b) The limiting slip condition occurs at the contact between A and B The maximum force before either block A or B slips is >

Q1/ The block shown is observed to have a velocity vą = 30 ft/s as it passes point A and a velocity vz = 15 ft/s as it passes point B on the incline. Determine the coefficient of kinetic friction between the block and the incline if x = 50 ft and 0 = 18°. B

A skier starts from rest on the 42° slope at time t = 0 and is clocked at t = 2.76 s as he passes a speed checkpoint 23 m down the slope. Determine the coefficient of kinetic friction between the snow and the skis. Neglect wind resistance. 42° The free-body diagram is shown. Find the normal force N and the friction force F. Your answers will be in terms of the mass m mg F

Small objects are delivered to the 78-in. inclined chute by a conveyor belt A which moves at a speed v₁ = 2.0 ft/sec. If the conveyor belt B has a speed v₂ = 6.1 ft/sec and the objects are delivered to this belt with no slipping, calculate the coefficient of friction uk between the objects and the chute. Answer: Uk= A i 24 78" B

The 10-lb block has a speed of 4 ft/s when the force of F = (8t²) lb is applied. The coefficient of kinetic friction at the surface is μ = 0.2.
