14) A train starts from rest and accelerates uniformly until it has traveled 6.4 km and acquired a forward velocity of 21 m/s. The train then moves at a constant velocity of 21 m/s for 400 s. The train then slows down uniformly at 0.065 m/s, until it is brought to a halt. The distance traveled by the train while slowing down is closest to 15) A catapult is tested by Roman legionnaires.

A car starts from rest and accelerates at a constant rate until it reaches 75 mi/hr in a distance of 220 ft, at which time the clutch is disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 570 ft with a deceleration which is proportional to its velocity. Find the time t for the car to travel the 790 ft.

What is the total distance traveled by the particle?
What Velocity vs. Time Graphs Can Tell You Constants A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors...
