Question

The distance record for someone riding a motorcycle on its rear wheel without stopping is more than 320000 m. Suppose the rider in this unusual situation travels with an initial speed of 8.00 m/s before speeding up. The rider then travels 40.0 m at a constant acceleration of 2.00 m/s2. What is the rider’s speed after the acceleration?

    Answer:

      v = 15.0 m/s

    Explanation:

    This is an exercise in kinematics in one dimension

              v² = v₀² + 2 a x

    in the exercise indicate that the initial velocity v₀ = 8.00 m / s

    the distance traveled during acceleration is x = 40.0 m

         

               

    let’s calculate

              v² = 8² + 2 2 40

              v = √ 224

               v = 14.97 m / s

               v = 15.0 m/s
