Two blocks collide on a frictionless surface. After the collision, the blocks sticktogether. Block A has a mass M and is initial
ly moving to the right at speed v. Block B has amass 2M and is initially at rest. System C is composed of both blocks. (a) Draw a free-bodydiagram for each block at an instant during the collision. (b) Rank the magnitudes of thehorizontal forces in your diagram. Explain your reasoning. (c) Calculate the change inmomentum of block A, block B, and system C.Anybody want to take a crack at this?
Total mechanical energy = kinetic energy + potential energy E = KE + PE E = ½mv² + mgh E = ½(0.1 kg)(2 m/s)² + (0.1 kg)(9.8 m/s²)(1.5 m) E = 0.2 J + 1.47 J E = 1.67 J
The equivalent resistance of n resistors in series is given by: In our circuit, we have three resistors of each, therefore the equivalent resistance of the circuit is
