A machine part is initially rotating at 0.500 rad/srad/s. Its rotation speeds up with constant angular acceleration 2.50 rad/s2rad/s2. Through what angle has the machine part rotated when its angular speed equals 3.25 rad/srad/s? Give your answer in radians.

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

The dot diagram represents the motion of the motorcycle as it moves from left to right

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?
