In the figure, two blocks are connected over a pulley. The mass of block A is 14.0 kg and the coefficient of kinetic friction between A and the incline is 0.320. Angle 0 of the incline is 46.0°. Block A slides down the incline at constant speed. What is the mass of block B? Frictionless, massless pulley B Number i Units Save for Later Attempts: 0 of 5 used Submit Answer

Power As shown in the picture below, you and a friend are pushing a box horizontally. You can assume that you and your friend are both pushing completely horizontally in this case. Your combined push force (from you and your friend) is Push = 46.0 N. The box has a mass of 20.0 kg. You and your friend push the box a horizontal distance of 6.50 m. There is a force of friction between the ground and the box with a value of f = 28.0 N. Assume that initially the box is at rest when you and your friend start pushing it. What is the rate at which all of the forces do work on the box? This is another way of asking about Power. You'll need acceleration to find the time - but you have enough information to calculate the acceleration.

ment Sharing Settings The 1.0 kg block in (Figure 1) is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is = 0.42.
