Question

As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The figure gives their
velocities v as functions of time t as the conductors slow the trains. The figure's vertical scaling is set by v, 46 m/s. The slowing
processes begin when the trains are 240 m apart. What is their separation when both trains have stopped?

An unwary football player collides head-on with a padded goalpost while running at 7.2 m/s and comes to a full stop after compressing the padding and his body by 0.28 m. Take the direction of the player’s initial velocity as positive Assuming constant acceleration, calculate his acceleration during the collision, in meters per second squared. How long does the collision last in seconds?
joe wants to test how fast can superman save him if he jumps of a cliff 180 m high. he recorded that after 5 seconds, superman arrives at the cliff and dives to save joe. superman leaves the cliff with an initial velocity to give him a push to catch joe, and later on act on a free fall as joe is. compute the initial velocity of superman so he can catc joe before they hit the ground.

Problem 5: a) What is the final velocity of a train that starts with a velocity of 4 m/s then accelerates at 0.05 m/s² for 8 minutes? b) Once at this speed, how long will it take the train to decelerate to a stop if it can slow at a rate of 0.55 m/s² when braking? c) What distance does the train travel while it is braking to a stop?
The 25-Mg boxcar A 16m/s to the right is coasting on the horizontal track when it encounters a 9-Mg car B coasting at 2m/s toward it. If the two cars meet and couple together, determin common speed in m/s just after the coupling. Please see details below. Rounding numbers to 2 decimal places at the end.
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.)
A boy runs for 24 seconds. During the first 8 seconds, his minimum speed is 2.6 m/s, while his maximum speed is 4.8 m/s. During the remaining time, his minimum speed is 4.8 m/s, while his maximum speed is 5.6 m/s. calculate the maximum (least upper bound) on the distance that he runs, in meters.
A distance of 60 meters separates two jetskis at Virginia Beach. Starting at rest, the jetskis accelerate at a constant rate of 0.2 m/s2 towards each other.Starting at a midpoint between the two jetskis, a porpoise is seen swimming from one jetski to the other at a constant speed of 16 m/s. The porpoise continues swimming back and forth between the jetskis until they crash together.a) What is the total distance the porpoise travelled? b) what is the speed of the jetskis when they crash together?
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.
