Acceleration of the rider = 0.799 m/s^2

Explanation:

We have equation of motion, v^2=u^2+2as , where u is the initial velocity, u is the final velocity, s is the displacement and a is the acceleration.

Initial speed of bicycle rider = 0 m/s

Final speed of bicycle rider = 8.24 m/s

Traveling distance = 42.5 meters.

Substituting

$8.24^2=0^2+2*a*42.5\\\\a=0.799m/s^2$

Acceleration of the rider = 0.799 m/s^2

The substance that would cold down the slowest at night would be d.sand - sand on the shore, because it heats up faster and gives away heat faster than water.
