1. In a nonuniform circular motion, what is the direction of the tangential acceleration if the moving particle has increasing velocity? a. Opposite with radial acceleration b. Same with instantaneous velocity c. Opposite with instantaneous velocity d. Same with radial acceleration 2. A roller coaster car moves with varying speed in a vertical loop. Assume that the loop is circular. At what point does the roller coaster car has decreasing velocity? (Refer to the photo)
