Homework Answers
now in this part we take intial velocity, U= 1.565 m/susing
conservation of energy
frictional energy loss= change in kinetic energy of system
-u(mg) d= 0.5m(v^2-U^2)
-0.2*12*9.8*0.5= 0.5*12*(V^2-1.565^2)
v= 0.699 m/s
comment in case any doubt..goodluck

Boxes A and B in (Figure 1) have masses of 13.8 kg and 4.9 kg , respectively. The two boxes are released from rest. Part A What would be the speed of the boxes when box B has fallen a distance of 0.50 m? The coefficient of kinetic friction between box A and the surface it slides on is 0.20. Use conservation of energy.

two boxes are connected by a
cord running over a pulley. The coefficient of kinetic friction
between box A and the table is 0.31. Ignore the mass of the cord
and the pulley friction. In this case we can assume that the force
applied to one end of the cord will have the same magnitude at the
other end. Find a) acceleration, b) the Tension force FT
in the cord. Assume box A is twice the mass of box B...

Problem 5.33 The coefficient of kinetic friction between a 50 kg crate and the warehouse floor is 80 % of the corresponding coefficient of static friction. The crate falls off a forklift that is moving at4 m/s and then slides along the warehouse floor for a distance of 3.5 m before coming to rest. Part A What is the coefficient of static friction between the crate and the floor? Express your answer to one significant figure. #PLEASE SHOW WORK

Question 8 A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank. She places the box on the plank and gradually raises one end of the plank. When the angle of inclination with the horizontal reaches 20°, the box starts to slip, and it then slides 2.2 m down the plank in 1.9 s at constant acceleration. What are (a) the coefficient of static friction and (b) the coefficient of kinetic...

You are lowering two boxes, one on top of the other, down the ramp shown in the figure (Figure 1) by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 18.0 cm/s . The coefficient of kinetic friction between the ramp and the lower box is 0.490, and the coefficient of static friction between the two boxes is 0.786. What force do you need to exert to accomplish this?...
