(question 11 in Newtons)
Question 11 4 pts A5 kg ball starts rolling from a top of a hill at 50 meters, assuming there is no friction involved, what is the kinetic energy of the ball at the bottom of the hill where the height is 0 meters? (Hint: use the conservation of energy idea).
Question 13 It takes a spring five full seconds to complete one oscillation when in earth, if we move the whole setup to Jupiter, how do you reckon the period of the oscillation will change? Will increase 4 pts O Will decrease O Period won't change at all
Question 14 For a 2 kg block of wood lying flat on a wooden table top, what is the coefficient of friction if 35 N of force was applied to overcome the static friction? (Hint: Look for the formula that relates u, frictional force and mass) 4 pts
