If the motorcycle can go from 0 to 50mph in 3 seconds the person is describing the motorcycle's acceleration.

Answer:

acceleration

Explanation:

He is describing the acceleration of motorcycle.

Here the initial velocity is zero, final velocity is 50 miles / hr, time taken is 3 sec.

Convert miles per hour into metre per second.

50 miles / hr = 22.352 m/s

using first equation of motion,

v = u + a x t

\(a = \left ( \frac{v - u}{t} \right )\)

\(a = \left ( \frac{22.352 - 0}{3} \right )\)

a = 7.45 m/s^2
