Two blocks, each of mass m = 6.90 kg , are connected by a massless rope and start sliding down a slope of incline θ = 40.0 ∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk = 0.350. At a distance d = 2.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks 4.10 s after the blocks have started moving? Assume...
A horizontal force of 80 N acts on a mass of 6 kg resting on a horizontal surface, as shown in Figure 5. The mass is initially at rest and covers a distance of 5 m in 0.92 s under the action of the force. Assuming there are no energy losses due to air resistance and therefore that the acceleration is constant (a) (b) (c) (d) Calculate the total energy expended in the acceleration. Plot a graph of the kinetic...
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right.Part (a) Solve numerically for the magnitude of the normal force, FN in newtons, that acts on the block if θ = 30°. Part (b) Solve...
