To use the principle of work and energy to determine characteristics of a system of particles, including final velocities and positions.
The two blocks shown have masses of mA
= 56 kg and mB = 74 kg . The coefficient of kinetic friction between block A and the inclined plane is μk = 0.15 . The angle of the inclined plane is given by θ = 40 ∘
. Neglect the weight of the rope and pulley.
Determine the magnitude of the normal force acting on block A, NA
If both blocks are released from rest, determine the velocity of block B when it has moved through a distance of s = 2.00 m.
If both blocks are released from rest, determine how far block A has moved up the incline when the velocity of block B is (vB)2 = 6.25 m/s.
