**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

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

SA3. A block is given an initial velocity of 5.00 m/s up a frictionless 20.0° incline. How far up the incline does the block slide before coming to rest? SA4. A man is pulling a crate along a concrete floor. This time, let's be specific. The crate has a mass of 100 kg and the man pulls with a force of 1 250 N. The coefficient of friction between the crate and the floor is 0.2. What is the acceleration of the crate? SA5. A horizontal force of 80 N is used to pull a 20 N wooden box moving toward the right along a horizontal, wood surface as shown. Calculate the magnitude of the frictional force acting on the box. Determine the magnitude of the force acting on the box. Determine the mass of the box. Calculate the magnitude of the acceleration of the box.
