As a horse finishes its trot around the corral, it slows from 4m/s to a stop in 3
seconds. Calculate the acceleration of the horse.
Can anybody help ?
Answer:
increases by a factor of 
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
