Answer 1

Answer #1

a(t) = (6 - t)

a) v = $\int$ a dt

v = $\int$ (6 -t) dt

= 6t - t^2 /2

b) distance = $\int$ v dt

= $\int$ ( 6t - t^2 /2) dt

= 3t^2 - t^3 / 6

begins A commuter train traveling at 45MPH is ómiles from the station. The train to decelerate so that its speed is 15MPH when it is 0.5miles from the station. Knowing that the train arrives at the station 14minutes after beginning to decelerate and assuming constant deceleration, find : a) time required for the train to travel the first 5.5 miles, b) the final deceleration of the train, c) the speed of the train as it arrives at the station.

A train on a straight track starts from rest t station A. It accelerates for 20 seconds with an acceleration of 5 m/s^2 and then continues to travel at the velocity reached for two minutes. The train then decelerates at 5 m/s^2 for 20 seconds before coming to a stop at the next station B. What is the distance between the two stations?

A light-rail train going from one station to the next on a straight section of track accelerates from rest at 1.20 m/s2 for 12.6 s . It then proceeds at constant speed for 1300 m before slowing down at 2.00 m/s2 until it stops at the station. What maximum velocity does the train achieve after leaving the station? What is the distance between the stations? How much time does it take the train to go between the stations?

A train begins at the origin and moves at constant speed v1=16.1 m/s toward another train which is initially at rest at a distance d=108 m from the first train. If the second train has an acceleration of magnitude a2=1.29 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
