Your are sitting in your car, which is standing at the side of the road with the engine idling. In the rearview mirror, you see one of your class mates approaching on a bicycle on the sidewalk. The moment the other student passes you, you start accelerating at 3.5 m/s2, while the bicycle continues to move along at a constant speed of 11.7 m/s. After what distance will you catch up with your classmate?
What are the following values about the central axis at the instant the torque has been applied for 195ms? The angular momentum of disk.
A luge and its rider, with a total mass of 83kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 44m/s. Assume that they stop with the constant deceleration of 2.9 m/s2.
