Aspacecraft is traveling with a velocity of v0x = 6580 m/s along the +x direction. two engines are turned on for a time of 907 s. one engine gives the spacecraft an acceleration in the +x direction of ax = 1.81 m/s2, while the other gives it an acceleration in the +y direction of ay = 8.05 m/s2. at the end of the firing, what is a) vx and b) vy?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

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
