Q1. What is the tangential acceleration of a bug on the rim of an 11.00 in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.03 rev/min in 3.60 s? One second after the bug starts from rest, what is its centripetal acceleration? One second after bug starts from rest, what is its total acceleration?
Q2. A 61 kg skateboarder is moving down a ramp with a 7.00 m radius of curvature. At the bottom of this ramp he reaches a speed of 7.80 m s.
