Question:

1. A block of mass m = 5.0 kg is pulled along a horizontal floor or up the ramp by a force of magnitude F = 50 N. The coefficient of kinetic friction between the block and surface is 0.15 and the magnitude of the angle θ = 25.0°.
(a) Make a free-body diagram of the block for each case.
(b) Calculate the magnitude of the normal force and kinetic friction force for each case.
(c) Calculate the acceleration of the block.


Answers

Horizontal Floor Normal Force frictional como F -50N foro b) Nornal force ng = 5 + 9.8 49N Kinetic friction force. Mng = 0.15
