Two blocks of masses 20 kg and 8 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 8-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s 2 what is the tension in the connecting string between the blocks?

Find the tensions in the two cords and the accelerations of the blocks as shown in the figure iffriction is negligible. The pulleys are massless and frictionless, mı=215g,m2=500g and m3=365g. m2 m3

Sam pushes toward the right on a box with a force of magnitude 31.0 N. Sarah applies an 11.0 N force on the box in the opposite direction. The magnitude of the kinetic friction force between the box and the very smooth floor is 4.50 N as the box slides toward the right. Also, the magnitude of the normal force is 98 N. Find the box's mass, the box's acceleration in the x-direction, the box's acceleration in the y-direction, and the coefficient of dynamic friction. Choose the correct answers m = 10 kg,a, = 2.55 m/s,a, = 0 m/s²,µ = 0.5 %3D

A 100 N force accelerates mass m1 by 15.0 m/s^2. The same force acts on another mass m2 by 25.0 m/s^2. What is the acceleration of the objects when their masses are joined at the same force?
