A5.00-kg block is placed on top of a 10.0-kg block (fig. p5.44). a horizontal force of 45.0 n is applied to the 10-kg block, and the 5-kg block is tied to the wall. the coefficient of kinetic friction between all moving surfaces is 0.200. (a) draw a free-body diagram for each block and identify the action-reaction forces between the blocks. (b) determine the tension in the string and the magnitude of the acceleration of the 10-kg block

Emily pulls a 5-kg block across a rough horizontal surface, exerting a constant force on the block. the magnitude of the force is initially 5 n, and the block moves at a constant velocity of 2 m/s. while the block is moving, emily instantly increases the force to 10 n. how will the block move now? andrew says: the block will move at a constant velocity of 4 m/s because it was initially moving with constant velocity and the final force is two times larger than the initial force. jasit says: the block will move at a constant acceleration of 2 m/s2 because the sum of the forces exerted on the block is 10 n and the mass of the block is 5 kg. mary says: the block will move at a constant acceleration of 1 m/s2 because the sum of the forces exerted on the block is 5 n and the mass of the block is 5 kg. part a which student is correct?
