Question 675091: If anyone could help me out it would be greatly appreciated. I am stumped here and would like to see the process of figuring this out.
A car is initially traveling at 20 m/s when it accelerates to 35 m/s in a time of 5 seconds. What is the acceleration of the car in m/s2?

You can put this solution on YOUR website!

Final velocity v+=35%28m%2Fs%29
Initial velocity v+%5Bo%5D=+20%28m%2Fs%29
Time t+=+5s
Acceleration a = ?m%2Fs%5E2

we can find the acceleration by the formula v=v+%5Bo%5D%2Bat:

v=v+%5Bo%5D%2Bat

35%28m%2Fs%29=20%28m%2Fs%29%2Ba%2A5s

35%28m%2Fs%29-20%28m%2Fs%29=a%2A5s

15%28m%2Fs%29=a%2A5s

a=15%28m%2Fs%29%2F5s

a=3%28%28m%2Fs%29%2Fs%29

a=3%28m%2Fs%5E2%29............ that is the acceleration
