A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.69 x 104 rad/s to an angular speed of 5.05 x 104 rad/s. In the process, the bit turns through 1.62 x 104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 8.11 x 104 rad/s, starting from rest

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
