g = 9.8 N/kg   a) If a pendulum (a mass swinging on the end of a string) is able to complete 13 cycles in 25 seconds (on Earth), how long is the string? b) If a 2.5kg mass is oscillating on a horizontal spring at a rate of 50 cycles in 120 seconds, what is the spring constant?  

g = 9.8 N/kg   1.  How do non conservative forces contribute to the way that we analyze the conservation of mechanical energy? 2. If a 3.25 kg rock falls from a 25m high bridge and 74% of the mechanical energy is conserved, how fast is it moving just before it hits the water?

g = 9.8 N/kg   A 1.95 kg mass compresses a spring 0.65m from its equilibrium position.  The spring has a spring constant of 485 N/m.  The spring is released and the mass is fired up a ramp that has a coefficient of friction of 0.55.  If the ramp has an angle of 25 degrees above the horizontal, how fast is the mass moving when it has experienced a change in height (vertical) of 0.65m?

Would you expect Precedent Transaction multiples to be greater or less than trading comp multiples? Explain.

Use the assumptions in the LBO question above, except KKR contributed $60,000 million of equity to the transaction. What is KKR’s resulting IRR when the PE firm exits in five years? Input your answer as a percentage. For instance, 18.2% would be inputted as 18.2 (not .182).
