- I need help with part D!!A student could either pull or push, at an angle of 30⁰⁰ from the horizontal, a 60 kgkg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.21. The crate is to be moved a horizontal distance of 25 mm A) Compared with pushing, pulling requires the student to do more, less, or the same work. B) Calculate the minimum work required for both pulling and pushing. Express your answers using two significant figures separated by a comma. Answer must be in J Wpulling, Wpushing =1. A 5kg block is push up a rough, inclined surface by a constant force of 20N. The surface is inclined at an angle of 15° and the force is applied completely horizontally and parallel to the ground below the incline. (Not parallel to the inclined surface). As a result, the velocity of the block increases from 0 m/s to 4 m/s in a displacement of 10m. A)What work was done by the frictional force during this displacement? B)What would have been the final velocity if friction was not present? C) Why was the final kinetic energy without friction higher than the total kinetic energy with friction?
