PLEASE HELP IM BEING TIMED A tortoise and a hare raced and the following number were recorded: The tortoise "ran" the entire 100 meter race at a steady pace of 0.2 m/s. The hare started from rest and accelerated at a constant rate of 0.4m/s^2 for the first 30 meters, then rested for 6 minutes, then finished the last 70 meters of the race at a steady speed of 0.5 m/s. How much time (in seconds) did the hare take to complete the race?

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

Place me with this question is my last question
