Question
Please show work, thank you so much for your help!
Block A of mass 2.0 kg is pulled along a horizontal table by a force of 15 N, which is applied by a light stFind theg that passes over a light frictionless pulley, as shown above. The coefficient of kinetic friction between the block and the surface is 0.25. On the dot below, which represents the block, draw and label the forces (not components) that act on the block as it is pulled across the table. Calculate the magnitude of the acceleration of the block.Explanation / Answer
a) forces on the block
tension in forward direction
frictional force in backward direction
mg in downward direction and normal force in upward direction
b) T - Uk*mg = m*a
=> a = (15 - 0.25*2.0*9.8)/2 = 5.05 m/s^2
