Determine what speed the motorcyclist develops in 15 seconds, moving from rest with an acceleration of 1.3 m / s2

Given:

a = 1.3 m / s ^ 2 – the acceleration of the motorcyclist;

t = 15 s – time of movement of the motorcyclist;

It is required to find V1 – the speed that the motorcyclist developed during the time t.

a = (V1 – V0) / t, or in this case, how did a motorcyclist start moving from a state of rest, that is, V0 = 0, a = V1 / t, hence:

V1 = a * t = 1.3 * 15 = 19.5 m / s.

Answer: the motorcyclist developed a speed of 19.5 m / s.
