**11. The three blocks in the figure are on a frictionless surface. If F= 48.0 N, m₁ = 2.0 kg, m2 = 1.5 kg, and m3 = 3.5 kg, what is the tension in the cord? m₁ m₂ m3 F

A 3.0 kg block moves up on a rough 20° inclined plane with µk = 0.43. A force of 16 N parallel to the incline and up the incline is applied on the block. What is the acceleration of the block?

In the figure, three masses are attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table. mA = 5.4 kg, mB = 6.2 kg, and mc = 10.7 kg. Find the tension in the cord to the right (between masses B and C) once the blocks have been released and are free to move. Your answer should be in N: Question Help: Read B

Blocks 1 and 2 are moving to the right on a frictionless surface by the tension TB = 36 N as shown. m1 = 2.0 kg, and m2 = 3.2 kg. What is the magnitude of the acceleration of block 2, in m/s²? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. m₁ TA m₂ TB

In the figure shown, the coefficient of kinetic friction between the block and the incline is 0.40. What is the magnitude of the acceleration of the suspended block as it falls?
