. = 5m/s/s-20-10=10 10/2=5 B.-what do you mean, friend?......
What is the acceleration of an object that changes velocity from 10 m/s to 20 m/s over a span of 2 seconds?

A. 50 m/s^2
B. 5 m/s^2
C. 5 m/s
D. 6 m/s^2

-
A = change in velocity minus time
Change in velocity = 10 m/s to 20 m/s= 20m/s - 10 m/s= 10m/s
time = 2 seconds
10 m/s divided by 2 seconds... = 5m/s/s

-
20-10=10 10/2=5 B.

what do you mean, friend?
