A block of mass m = 1.0 kg is placed at rest at a distance 8.15 m (measured along the slope) from the horizontal plane on an incline whose surface makes θ=25o to the horizontal as shown in Figure 2. The coefficient of kinetic friction between the surface where the block is placed and the block is μk = 0.19. After the block starts descending on the slope, find the block’s speed at the time when it reaches the bottom...

1) Consider two boxes: box B, with a mass of 3kg, placed on top box A, with a mass of 10kg. If box A is pushed with a force of 70N, what is the force of friction on box B? The coefficients of friction between boxes A and B are µs = 0.7 and µk = 0.4, while friction is negligible between box A and the ground. 2) A 1.5kg box is pushed up a 30o incline with a force...
Question 6 2 points Save Answer A box of mass m = 2.04 kg is attached to a spring (see figure). The spring constant is ks = 200 N/m, but the friction coefficient uk between box and surface is unknown. When the spring is stretched by a distance Xo = 0.400 m relative to its relaxed position and then released (from rest), the spring contracts so that the box is again momentarily at rest when the spring is most squeezed,...
