Question

9 is pulled by a rope at 30 degrees angle relative to the 0.10 3) A cart of mass M- 15.0 kg a rope at horizontal. The coefficient of frictions is given: μ.-0.20 and k For all the 3 following parts you must show all force acting on the object. And start the problem by using second 12 points / each question 4 points g Newtons second Law F- m a to prove the formula for your solution. a) Show all the force vectors acting on the cart on the above figure. Resolve T in X and Y direction. c) Use Newtons second Law to derive a formula for T the tension in the rope when the object starts moving to the right d) Use the formula for T from part b to find the magnitude of T

    im A rope at an angle θ with the horizontal is pulled with a force UF. It pulls, in turn, two blocks, the bottom with mass M and the top with mass m. The coefficients of friction are p, between the top and bottom block (assume that they do not slide for the given force ) and pu between the bottom block and the table. Remember to show (and possibly evaluate) all forces acting on both blocks, including internal forces...

Assume that the rope and pulley are massless and that there is no friction in the pulley. If the masses have the values m = 18.7 kg and m2 = 13.7 kg, find the magnitude of their acceleration a and the tension in the rope. Use g -9.81 m/s Newton's second law...
