Explanation:
<u>Motion with Constant Acceleration</u>
A body moves with constant acceleration when the speed changes uniformly in time. The equation used to find the final speed vf is
![v_f=v_o+at](https://tex.z-dn.net/?f=v_f%3Dv_o%2Bat)
Where vo is the initial speed, a is the acceleration, and t is the time.
The cyclist has an initial speed of vo=10 miles/hour and ends up at vf=20 miles/hour in t=5 seconds.
Both speeds are given in miles/hour and we must convert it to m/s:
1 mile/hour = 0.44704 m/s
10 mile/hour = 4.47 m/s
20 mile/hour = 8.94 m/s
The acceleration is calculated by solving for a:
![\displaystyle a=\frac{v_f-v_o}{t}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7Bv_f-v_o%7D%7Bt%7D)
![\displaystyle a=\frac{8.94-4.47}{5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7B8.94-4.47%7D%7B5%7D)
![a = 0.894\ m/s^2](https://tex.z-dn.net/?f=a%20%3D%200.894%5C%20m%2Fs%5E2)
