In the first 3 seconds of movement, the motorcyclist developed a speed of 6 m / s. what speed will the motorcyclist have in 5 seconds?
Initial data: t1 (first acceleration time of the motorcyclist) = 3 s; V1 (the speed that the motorcyclist developed during the time t1) = 6 m / s; t2 (second acceleration time) = 5 s.
1) Let’s define the acceleration with which the motorcyclist developed speed: a = V1 / t1 = 6/3 = 2 m / s2.
2) Let’s calculate the speed that the motorcyclist will have after 5 s: V = V1 + a * t2 = 6 + 2 * 5 = 16 m / s.
Answer: After 5 seconds, the motorcyclist will have a speed of 16 m / s.
