Explanation:
First we need to find the initial velocity for it to stop at the distance 2d using the following equation of motion:
where v = 0 m/s is the final velocity of the package when it stops, is the initial velocity of the package when it, a is the deceleration, and
is the distance traveled.
So the equation above can be simplified and plug in Δs = d, for the 1st case
(1)
For the 2nd scenario where the ramp is changed and distance becomes 2d,
(2)
let equation (2) divided by (1) we have:
So the initial speed increases by . If the deceleration a stays the same and time is the ratio of speed over acceleration a
The time would increase by a factor of
