Dominic Toretto is traveling at a constant acceleration of 3.94 m/s2 starting from rest. At the same instant, Brian O'Conner who is traveling at a constant speed of 16 m/s overtakes and passes Dom. Find the velocity of Dom's car when he overtakes Brian.   Round your answer to 2 decimal places.

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.)

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

3) It is a velocity-time graph for an object under constant acceleration. Determine the displacement of the object over the interval 0 s to 3.0 s, 3.0 s to 5.0 s, 5.0 s to 7.0 s. Determine the total displacement. Determine the accelerations of object over the interval 0 s to 3.0 s, 3.0 s to 5.0 s, 5.0 s to 7.0 s. What is the average velocity during the interval 0 s to 4.0 s? Draw the graphs of position-time if its initial position be zero. Draw the graphs of Acceleration-time. v (m/s [E]) 1.2 1.0 0.8 0.6 0.4 0.2 0+ 0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 t(s)
