I need solve this homework of physics ii

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 33.2 N. If m, = 17.4 kg, m2 = 26.0 kg, and m3 = 31.3 kg, calculate (a) the magnitude of the system's acceleration, (b) the tension T1, and (c) the tension T2- (a) Number i Units Q7 (b) Number i Units (c) Number i Units Two blocks are in contact on a frictionless table. A horizontal force is applied to the larger block, as shown in the figure. (a) If m1 = 2.6 kg, m2 = 1.6 kg, and F = 3.8 N, find the magnitude of the force between the two blocks. (b) Assume instead that a force of the same magnitude F is applied to the smaller block but in the opposite direction, and calculate the magnitude of the force between the blocks. (Why is the value calculated in (b) not the same as that calculated in (a)?) F Q8 (a) Number i Units (b) Number Units The figure gives, as a function of time t, the force component F , that acts on a 2.70-kg ice block that can move only along the x axis. At t = 0, the block is moving in the positive direction of the axis, with a speed of 2.00 m/s. What is its velocity, including sign, att = 11 s? F. (N) 1 ( 5 ) 12 Q10 Number i Units
