I need ans to be correct and fast Fmm mTwo identical blocks of mass m are connected with a massless spring and placed on a horizontal and frictionless table. The two blocks-springsystem is initially at rest. At the instant t = t, a horizontal and constant force of magnitude F is applied to the left block. At a later time t = t2the force is removed.(Part a) What is āem, the acceleration of the center of mass of the 2 blocks + spring system after the force is removed (for t > tą)? Express youranswers in some or all of the following: m, F, Deltat for At = t2 – t1, and hati for i.dem(Part b) What is vem, the velocity of the center of mass of the 2 blocks + spring system after the force is removed (for t > t2)? Express youranswers in some or all of the following: m, F, Deltat for At = tz – tı, and hati for i.Vem(Part c) What is the speed of the blocks at the instant when the spring is at maximum compression ?O Both blocks are momentarily at rest therefore their speeds are both zero.O The same as the speed of the center of mass of the system.O Half the speed of the center of mass because they have equal masses.O Not enough information.

In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). V. o h d The top of a pool table is a height h = 3.25 ft from the floor. If a player's ball lands a distance d 14.75 ft from the table edge, what is her break shot speed vo? 12.3 Vo = mph Incorrect At what speed v did her pool ball hit the ground? 4.21 mph = Incorrect
