Asolid block of mass 16 kg slides down a ramp from a height of 4.9 m on to a smooth horizontal floor where it encounters a frictional force of 38.2 n. using the principles of mechanical energies, and the work done by dissipative forces like friction, calculate how long is the distance traveled across the floor until it comes to a stop? (assume g=9.8 and the mass of the block is needed for this calculation)
