A box of mass 20 kg moves up a rough plane which is inclined to the horizontal at 25.0o .It is pulled by a horizontal force F of magnitude 250N . The Coefficient of kinetic friction between thr box and the plane is 0.300 a) if the box travels 3.80 m along the plane determine i. The work done on the box by the force F ii. The work done on the box by gravitational force iii. The work done on the box by reaction force and the work done on the box by frictional force v. total work done on the box b) If the speed of box is zero at bottom plane ,calculate it speed when it travellef 3.80 m (given g=9.81m/s2)
A 60 kgm body has a potential energy if 135 Kcal with respect to a datum plane X and a potential energy of 99 Kcal with respect to a datum planebY. If the local acceleration of gravity is standard, compute the relative position of the plane X relative to plane Y. Reaolve the problem if g=30 fps^2.
A block of mass m, lies on the floor of an elevator cab of mass m, that is being pulled upward by a cable through a distance d. During this displacement, if the normal force on the block from the cab's floor has constant magnitude FN, how much work is done on the elevator cab by the force T from the cable (W, )? Express your answer in terms of m, m2, FN, and d. T m. Select one: W= Fyd(1 - m) W, Fyd( ) |3D Fyd(1 +m) %3D End(im
