Miguel found the section:

A train decelerates uniformly from a speed of 108 km/h to rest in 20 seconds. Find its deceleration and the distance traveled.

Compute positions: [ s(0) = 2,\ s(1) = 1 - 6 + 9 + 2 = 6,\ s(3) = 27 - 54 + 27 + 2 = 2,\ s(5) = 125 - 150 + 45 + 2 = 22 ] Displacement = ( s(5) - s(0) = 22 - 2 = 20 ) m (positive, to the right). I encourage you to visit and explore its

A train moves along a straight track with an initial velocity of . It accelerates uniformly at . Calculate the final velocity and total distance traveled. Solution: Identify given variables: Find final velocity ( ): v=v0+atv equals v sub 0 plus a t

"Pens down. Pass your papers forward," the proctor commanded.

A car starts from rest and accelerates at ( 2 , \textm/s^2 ). At the same instant, a truck moving at constant speed ( 10 , \textm/s ) overtakes the car. How long will it take for the car to catch up with the truck, and how far will the car have traveled? Find its deceleration and the distance traveled

He wrote the final answer clearly:

: Solving for velocity and acceleration when position is given as a function of time, such as

The negative sign indicates the displacement is from the bridge, which is the bridge's height above the water.
