A constant applied force Fp of 15.0 N pushes a box with a mass m = 8.00 kg a distance x = 15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is 0.150. Fp m Assuming that the box starts from rest, what is the final velocity of of the box at the 15.0 m point? If there were no friction between the box and the floor, what applied force Fnew would give the box the same final velocity? x m/s Uf = Fnew = N

A mover is pushing a 148kg box up a ramp. The ramp is inclined at an angle of 30.4 degrees. Since the box is on wheels, assume that friction is negligable. Calculate the force the mover exerts to push the box up the ramp at a constant rate of 1.26 m/s. Assume he pushes parallel to the ramp.

The 3500-lb automobile shown in the picture is traveling down the 10-degree inclined road at a speed of 20 ft/s. If the driver wishes to stop the car, determine how far s the tires skid on the road if the brakes are jammed, causing the wheels to lock. Coefficient of kinetic friction between wheels and road is 0.5.

wo blocks are positioned on surfaces, each inclined at the same angle of 52.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.16 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.440. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?     2.34 kg     1.66 kg     10.38 kg     5.97 kg

Objects with masses m1 = 13.0 kg and m2 = 6.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m2falls 1.00 m in 1.37 s, determine the coefficient of kinetic friction between m1 and the table.

Jill of the Jungle swings on a vine 7.00 m long. (a) What is the tension in the vine if Jill, whose mass is 65.0 kg, is moving at 3.00 m/s when the vine is vertical? (b) If the maximum tension that the rope can support is 750 N, what is the maximum speed that you can have on the rope?

An object moves up an inclined surface with angle 37° at initial speed 20m/s. Thecoefficient of friction is 0.3. Find the distance the object moves up the surface before itstops. What is the time required to move this distance? If the object now slides down theinclined surface , what is the time required to reach its initial point where it wasprojected?

What is the coefficient of kinetic friction μk between the block and the tabletop?

A block slides down an incline of 30.0∘ to the horizontal at a constant velocity. What is the coefficient of dynamic friction between the block and the incline? Give your answer to 3 significant figures

A 945.0kg car traveling rightward at 22.6 m/s slams on the brakes and skids to a stop (with locked wheels). If the coefficient of friction between tires and road is 0.9710, determine the force of friction. Use correct number of significant figures in answer Force =
