A toy car of mass 100. g is launched from a track at an unknown angle θ. 1.5 meters away from the ramp, at the maximum height of its jump, it is caught by a net attached to a light (mass-less) rotating rod of length 20.0 cm which causes the car to rotate in circular motion. A force meter attached to the rod reads 5.0 N as it spins. (a) Determine the height h of the net. (b) Determine the initial velocity vi the car was launched at.

Question

A toy car of mass 100. g is launched from a track at an unknown angle θ. 1.5 meters away from the ramp, at the maximum height of its jump, it is caught by a net attached to a light (mass-less) rotating rod of length 20.0 cm which causes the car to rotate in circular motion. A force meter attached to the rod reads 5.0 N as it spins.

(a) Determine the height h of the net.
(b) Determine the initial velocity vthe car was launched at.
