Two skaters, one with mass 55 kg and the other with mass 45 kg, stand on an ice rink holding a pole of length 14 m and negligible mass. Starting from the ends of the pole, the skaters pull themselves along the pole until they meet. How far does the 45 kg skater move

What determines the amount of inertia an object has

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
