A block of mass 50 kg is pulled up a slope with constant speed by applying an external force of 20 kgf parallel to the slope. The block moves through a distance of 4 m along the slope. i) What is the work done by the external applied force? ii) What is the energy stored when it reaches the vertical height of 3m (g = 10m/s2) |
