1. A spring (k=100 N/m) is hanging from the ceiling when somebody attaches a 2 kg block to theend of it and releases it.a. Identify all of the forces on the block after it is released.b. Which forces are in the direction of motion and which are in the opposite direction ofmotion? Which forces are doing positive work and which are doing negative work?c. Write an integral for the work done by gravity as the block falls from s=0 to s=x₁. Solve theintegral with the start and end points at s=0 and s=xf.d. Write an integral for the work done by the spring as the block falls from s=0 to s=xf. Keepthe signs correct. Solve the integral with the start and end points at s=0 and s=x₁.e. Use the work-kinetic energy theorem AK-Wnet to determine how low the block falls beforeturning around. (Note: the block has no velocity at its lowest point).f. When the block was first falling, what was its velocity when the spring stretched 20 cm?
