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
