In the figure, a very small toy race car of mass m is released from rest on the loop-the-loop track. If it is released at a height 2R above the floor, how high is it above the floor when it leaves the track, neglecting friction? 2R O 1.50 R O 2.00 R O 1.33 R O 1.67 R O 1.25 R

Question 10 A1 kg skate rat drops from the top of a 3 m high half-pipe ramp. Ignoring friction, how much Kinetic Energy would s/he have at the lowest point of the ramp? O 100 Joules 300 Joules 3 Joules 30 Joules Question 11 Ignoring friction, what would be the velocity of the skate rat in the question above at the lowest point of the ramp? 60 600 m V3m 303 Question 12 In the real world, the skate rat above would loose some speed/energy due to friction, if it looses 10 Joules of energy while moving from on side of the ramp (where s/he dropped in) to the other side of the half-pipe, how far (in meters) would the skate rat make it up the other side?

In Q7, what is the magnitude of the work done by the external force after 5 seconds?

In the figure, a frictionless roller coaster car of mass m = 832 kg tops the first hill with speed vo = 19.0 m/s at height h = 44.0 m. What is the speed of the car at (a) point A, (b) point B, and (c) point C? (d) How high will the car go on the last hill, which is too high for it to cross? Use g=9.81 m/s2.
