An initially stationary device lying on a frictionless floor explodes two pieces, which then slide across the floor, one of them in the positive x direction. a) What is the sum of the momenta of the two pieces after the explosion? b) Can the second piece move at an angle to the 3 axis? c) What is the direction of the momentum of the second piece?

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

What organization and environment is described above?

An object with a mass of 1.5 kg changes its velocity from + 15 m/s to +22 m/s during a time interval of 3.5 seconds. what impulse was delivered to the objects?
