Now the blocks with the same masses are big enough to touch each other, and the sides of the string make the same angle from vertical. The coefficient of kinetic friction between them isμ. Assume that the blocks have velocity in the same direction as the acceleration you found above. Find the magnitude of tension T (N) in the string. Question 13 Homework. Unanswered.

The man pushes on the roller with force P through a handle that connects to the central axle of the roller. If the coefficient of static friction between the 69-lb roller and the floor is g = 0.11, and the force Pis maximum so that the roller is about to slip, determine the angular acceleration of the roller (in rad/s²). Assume the roller to be a uniform cylinder. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g = 32.2 ft/s². P Your Answer: Answer 30° 1.5 ft S

QUESTION 11 A small box of mass m is placed on top of a larger box of mass 2m as shown in Figure. When a force is applied to the large box, both boxes accelerate to the right with the same acceleration. If the coefficient of friction (static/kinetic) between all surfaces is u, what would be the magnitude of the force and what would be the acceleration ? m F 2m O 1.3m( µ+ g), g O 2.3µmg, µg O 3. 6umg, µg O 4. The information given in the problem is insufficient.

Block B rests on an A wedge. When the system is released and block A and B Since the static friction coefficient between them is μs and the kinetic friction coefficient is μk;a) Find the acceleration of block B.b) Find the relative velocity of B with respect to A at t=0.5 seconds. NOTE=There is no friction between the wedge A and the surface.

Question 2 A car has a mass of 4 Mg and the center of mass at G = 400mm from the ground. The front wheels are 1.3 m and rear wheels are 0.8 m from the centre of gravity. Coefficient of kinetic friction between the wheels and the road is 0.2. Determine the acceleration if the rear driving wheels are always slipping and the front wheels are free to rotate. Neglect the mass of the wheels.

consider the mass and pulley system in the attached file. mass m1 = 29 kg and mass m2 = 12kg. the angle of the inclined plane is given and the coefficient of kinetic friction between mass m2 and the inclined plane is uk = 0.12. assume the pulleys are massless and frictionless what is the acceleration of mass m2 on the inclined plane? take positive acceleration to be up the ramp a2 = ?
