1) A string is used to pull a 30kg box up a rough slope, as shown in the figure below. The box starts at rest at the bottom of the slope and is accelerated (with constant acceleration) to a velocity of 2 m s-1 over a distance of 6.0 m. The slope is at an angle of 35° and the coefficient of friction between the slope and the box is 0.64. The cable is at a slight incline of 25° above the slope. (a) By resolving forces, calculate the tension in the string during the constant acceleration in N.

A 5.0-kg box is pulled across a horizontal floor by a rope that is 20° to the horizontal as shown in Figure 1. The box has motion to the right. The tension in the rope is 50 N. 1) What is the magnitude of the normal force on the box? 2) If the coefficient of kinetic friction is 0.70, what is the magnitude of the friction force on the box? 3) What is the magnitude of the x-component of the tension force? 4) What is the acceleration of the box?

A 7.00-kg box is attached to a 3.00-kg box by rope 1. The 7.00-kg box is pulled by rope 2 with a force of 25.0 N. Determine the acceleration of the boxes and the tension in rope 1. The coefficient of friction between the ground and the boxes is 0.120.
A box of mass m1 = 8.8 kg on a rough inclined plane of angle α = 36° is connected with a string of negligible mass over a pulley in shape of a disk with a moment of inertia I = 1/2 * mpulley * R^2 to a bucket of mass m2 = 1 kg. The coefficient of kinetic friction between the block and the surface of the incline is μk = 0.2. If the mass of the pulley is mpulley = 2.5 kg. 1. Calculate the tension in the string T1. 2. Calculate the tension in the string T2. 3. Calculate the acceleration of the system: a.
