Determine what speed motorcyclists develop in 15 seconds, moving from rest with an acceleration of 1.3 m / s2.

These tasks: t (the duration of the motorcyclist’s acceleration) = 15 s; the movement of the motorcyclist under consideration from a state of rest (V0 (initial speed) = 0 m / s); a (acceleration) = 1.3 m / s2.

The speed that the motorcyclist will have time to develop in 15 seconds of acceleration is calculated by the formula: V = a * t.

Calculation: V = 1.3 * 15 = 19.5 m / s.

Answer: In 15 seconds, the motorcyclist will have time to develop a speed of 19.5 m / s.
