Question

A 10,000-kg truck coasts to a stop from a speed of 40m/sec. The truck's motion obeys the equation V= ve^(-(k/m)t) with k=200kg/sec.

a. about how far will the truck coast before reaching a complete stop?(round to the nearest whole meter)

b. about how long will it take the truck's speed to drop to 7m/sec? (round to the nearest 0.1 sec.)

A 95-kg cyclist on a 8-kg bicycle starts coasting on level ground at 24 m/sec. Use v=v, e-k/mt, where k is about 3.9 kg/sec. a. About how far will the cyclist coast before reaching a complete stop? b. How long will it take the cyclist's speed to drop to 7 m/sec? The cyclist will coast meters before reaching a complete stop.

12) Suppose that an Iowa class battleship has mass around 52,000 metric tons (52,000,000 kg) and a k-value in the equation of about 60,000 kg/s, where v is the ship's velocity, is the initial velocity, m is the mass, k is a constant of proportionality, and t is time. Assume that the ship loses power when it is moving at a speed of 9 m/s a. About how far will the ship coast before it is dead in the water?...
