Question

A rabbit runs in a straight line with a velocity of +1.7 m/s for a period of time, rests for 12 s, and then runs again along the same line at +0.59 m/s for an unknown amount of time. The rabbit travels a total distance of 1248 m, and its average speed is 0.84 m/s. What is the total time the rabbit spends running at 1.7 m/s? s How long does it spend running at 0.59 m/s? s A flatbed railcar is moving at a slow but constant velocity. A man stands in the railcar, facing sideways (perpendicular) to the motion of the railcar. The man holds a baseball at arm's length and drops it onto the railcar bed. Where does the principle of inertia predict that the ball will land? Explain. (Neglect any effects of air resistance.) The ban lands slightly behind the drop point on the railcar because the ball has a greater vertical velocity than the man and the railcar. The ban lands slightly in front of the drop point on the railcar because the ban has a greater vertical velocity than the man and the railcar. The ban lands directly below the drop point on the railcar because both the man and the baseball share the same constant horizontal velocity as the railcar.

Explanation / Answer

a) 340.99871 s

b) 1132.71558 s

The ball lands directly below the drop point on the railcar because bath man and baseball share same constant horizantal velocity as the railcar.
According to its inertia after droping it tries be in state of uniform motion.
