The coefficient of kinetic friction between the surface and the largest block is 0.20, and the coefficient of kinetic friction between the surface and the smaller block is 0.40. If F=25 N and M=4.0kg in the figure, what is the tension (in N) on the connecting string

A block with mass m1 = 4.50 kg and a ball with mass m2 = 8.00 kg are connected by a light string that passes over a frictionless pulley, as shown in figure (a). The coefficient of kinetic friction between the block and the surface is 0.300.

Find the acceleration of the two objects and the tension in the string.

Two blocks are connected by a string as shown in the figure. What is the upper block's acceleration if the coefficient of kinetic friction between the block and the table is 0.3?

The lower block in is pulled on by a rope with a tension forceofF = 31 N.The coefficient of kinetic friction between thelower block and thesurface is 0.40. The coefficient ofkineticfriction between the lower block and the upper block isalso 0.40.What is the accelerationof the 2.0 kg block
