Starting from the first floor, a lift stops at floors 3, 4,3, 2, 3, and 4 before returning to the first floor.
When two consecutive floors are the same, it means that the elevator stayed on the same floor on that segment of the trip.
If the distance between the first and sixth floors is 17 m, what is the total distance, d (in m), travelled by the lift?
Just enter the number below, correct to one decimal place, without the units.

1d. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure.
Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.)

If you have taken calculus, you know that we can find the velocity of the object by taking the derivative of the preceding equation. That is, dx = v = dt = gt We can find the acceleration by taking the derivative again: dv = a = g dt (a) Create a function called free_fall with a single input vector t that returns values for distance x, velocity v, and acceleration g.
