An aluminum block of mass m1 = 2.00 kg and a copper block of mass m2 = 6.00 kg are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in Figure P5.46, where θ = 30.0°. (a) When they are released from rest, will they start to move? If they do, determine (b) their acceleration and (c) the tension in the string. If they do not move, determine (d) the sum of the magnitudes of the

You find it takes 190 N of horizontal force to move an unloaded pickup truck along a level road at a speed of 2.4 m/s . You then load up the pickup and pump up its tires so that its total weight increases by 42%while the coefficient of rolling friction decreases by 19%. Now what horizontal force will you need to move the pickup along the same road at the same speed? The speed is low enough that you can ignore air resistance..
An 8.00 kg box sits on a ramp that is inclined at 33.0 above the horizontal. The coefficient of kinetic friction between the box and the surface of the ramp is mk = 0.300. A constant horizontal force F = 26.0 N is applied to the box, and the box moves down the ramp. If the box is initially at rest, what is its speed 2.00 s after the force is applied?
A 5.00 kg box sits at rest at the bottom of a ramp that is 8.00 m long and is inclined at 30 degrees above the horizontal. The coefficent of kinetic friction between the box and the surface is 0.40, and coefficent of static friction is 0.43. What constant force F, applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 6.00 seconds?
