A hot wheels track has a spring loaded launcher. A 100g car is pushed into the launcher, which compresses the spring by 2cm. The cars initial velocity after launching is 3m/s.
A) what are the energy conversions from beginning to the end of the track.
B) what is the spring constant of the launcher.
C) the car approaches a loop with a radius of 10cm. What is the speed at the top.
D) after the loop, the car approaches a ramp with height 20cm and an angle of 90 degrees. What height does the car reach?
E) what if the ramp was at 45 degrees.
F) what is the cars speed when it reaches the ground
G) how much compression would you need to get the car to reach 1m (of the vertical ramp)
