Answer: acceleration is 0.5 m/s^2
Explanation: From the question, we are given the following parameters
Time t = 20s
Initial velocity U = 0
Final velocity V = 10 m/s
Using first equation of motion,
V = U + at
Where a = acceleration
Substitute all the parameters into the formula to get acceleration a
10 = 0 + 20a
10 = 20a
Make a the subject of formula
a = 10/20 = 0.5 m/s^2
The acceleration is 0.5 m/s^2
