Problem 4 A block of mass m 15 kg is pulled along a horizontal frictionless floo

Question

Problem 4 A block of mass m 15 kg is pulled along a horizontal frictionless floor by applying a force F = 20 N at an angle theta = 25 Degree . (a) What is the magnitude of the blocks acceleration? (b) If the magnitude of F is slowly Increased, what is value. Just before the block is lifted (completely) off the floor? (C) What is the blocks acceleration just before it is lifted (completely) off the floor? Draw all free body diagrams necessary for your solution problem 58 If the coefficient of kinetic friction is 0.2 what are the magnitude of F and normal forces on the . block in Problem 4?

Explanation / Answer

a block of mass 15.00 kg is pulled along a horizontal frictionless floor by a cord that exerts a force F = 20.0 N at an angle ? = 25.0
