In the figure, m1 = 10kg and m2= 4.0 kg. the coefficient of static friction between m1  and the horizontal surface is 0.50 and the coefficient of kinetic friction is 0.30. a) id the system is set in motion with m2 moving downward, how much will be the acceleration of the system and the tension of the rope? g= 10m/s2

Situation 5: Suppose the coefficient of kinetic friction between me and the plane as shown in figure is µ = 0.2 and that m = 20 kg and m² = 20 kg 53. What is the acceleration of Block A 0.605 -0.605 0.303 -0.303 60° 54. What is the tension on the chord? 80.31 N 72.12 N 78.17 N 66.71 N 1.1 m/s 52. What is mass of block B in order to move 1m up in an inclined when the block initially at rest 18.83 kg 20.41 kg 15.61 kg 25.12 kg 30° 55. What is the time required for block B to reach the top assuming it is initially 2.5 m away. 4.06 S 1.07 s 2.87 s 3.24 s

A block having a mass of 60kg is subjected to a force, P =337.5N acting 53 degrees from the horizontal that causes it to have an acceleration of 1.2m/s2. Determine the coefficient of kinetic friction.NOTE: use 3 decimal places

A crate has a mass of 120kg and the coefficient of static and kinetic friction is 0.60 and 0.50, respectively. The crate starts from rest and the motor exerts a tension T= 1220 + 200t (N). If the elevation of the dock is 30 degrees from the horizontal, What is the velocity of the crate after 1sec? Compute the power transmitted after 1sec. Provide FBD. Thank you.
