14. The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.70 m tall and that the nerve impulse travels at uniform speed.)
1. Suppose that the velocity of a particle in motion is given by v(t) = 44t² +²+1 feet per second, where t is in seconds from now. Find the position of the particle after 5 seconds.
6. The acceleration due to gravity on the surface of the Moon is only 17% of that on the surface of the Earth. If a person can throw a heavy ball 10.0 m vertically upward on Earth, how high could she throw it on the Moon if she gives it the same starting speed? How much longer would it be in motion (up and down) on the Moon compared to on the Earth? A
