An airplane with mass 200,000 kg is traveling with a speed of
268 m/s the kinetic energy of the plane speed is 7.18 x 10'J.
A wind picks up, which causes the plane to lose 1.20 x 10 J per
second. How fast is the plane going after 25.0 seconds?
a
250.207 m/s
b 204.509 m/s
c
190.423 m/s
d
144.527 m/s

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
