Answer:
3
Explanation:
the change in velocity is 15, and if I'm right which I may not be you divide your change in velocity by your speed being 5 and get 3. i googled the equation to find acceleration and found a = v/t. this could be absolutely wrong but I hope it helps
Answer: Dr. William Herbert Sheldon
The Sheldon Coin Grading Scale is an internationally accepted, 70-point assessment of a coin's condition and quality. It was originally developed by Dr. William Herbert Sheldon in 1949 in order to grade large cents. His scale was slightly modified in the 1970s to account for a wider range of coins.

Answer:
Explanation:
I assume that by "velocity" you refer to the average velocity of the man during the trip.
In that case, we have the following data:
(average velocity)
s = 0.8 km = 800 m (distance covered by the man)
Therefore, we can find the total time of the trip by using
Now, we know that the motion during this trip is a uniformly accelerated motion, so we can find the acceleration by using the suvat equation:
where
u = 0 is the initial velocity (the man starts from rest)
a is the acceleration
Using s = 800 m and t = 114.2 s, we find:
