A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds
valentina_108 [34]
To find the acceleration of the bicycle rider, we are going to use the acceleration formula: a= \frac{v_{f}-v_{i}}{t}
where
a is the acceleration 
v_{i} is the initial speed 
v_{f} is the final speed 
t is the time 

We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore, v_{i}=5, v_{f}=15, andt=10. Lets replace those values in our formula:
a= \frac{v_{f}-v_{i}}{t}
a= \frac{15-5}{10}
a= \frac{10}{10}
a=1

We can conclude that the acceleration of the bicycle rider 1 m/s^2
