Question1

A ball of mass 10 kg and a ball of mass 1000 kg are ?oating in empty space, connected by a spring of negligible mass and force constant k = 10000 N/m. At a assured instant, spring has been stretched a distance such that the force it exerts on the 10 kg ball is 100 N. What force does spring exert on 1000 kg ball?

Question2

Describe in words how you use your calculator and your brain to solve the equation Tan (theta) = Vy/Vx for theta. How do you establish the value of theta when theta is greater than 90 degrees? Better than 180 degrees? Give two examples where you pick values for Vx and Vy and explain for theta illustrating when theta is greater than 90 degrees and while theta is greater than 270 degrees.
