With what acceleration does the motorcyclist go if in 4.5 sec. Does he pick up speed of 75 km / h from rest?

The acceleration of a motorcyclist during uniformly accelerated movement can be calculated by the formula:

a = (V – V0) / t, where V is the final speed of the motorcyclist (V = 75 km / h = 75 * 1000/3600 = 20.83 m / s), V0 is the initial speed of the motorcyclist (the motorcyclist began to gain speed from the state rest, V0 = 0 m / s), t is the acceleration time (t = 4.5 s).

Let’s calculate the acceleration of the motorcyclist:

a = (V – V0) / t = (20.83 – 0) / 4.5 = 4.63 m / s2.

Answer: The acceleration of a motorcyclist is 4.63 m / s2.
