Circular motion
The drawing shows a version of the loop-the-loop trick for a small car. If the car is given an initial speed of 5.0 m/s, what is the largest value that the radius r can have if the car is to remain in contact with the circular track at all times?

physics
The power needed to accelerate a projectile from rest to its launch speed v in a time t is 48.0 W. How much power is needed to accelerate the same projectile from rest to a launch speed of 2v in a time of 1/2t
