How long does it take to increase the speed of the car from 5 to 20 m / s with an acceleration of 0.75 m / s2?

The vehicle speed can be calculated using the formula:
V = V0 + a * t, where V is the final speed of the machine (V = 20 m / s), V0 is the initial speed of the machine (V0 = 5 m / s), and is the acceleration of the machine (a = 0.75 m / s² ), t is the time of movement of the machine (s).
Let us express and calculate the time of movement of the car:
V = V0 + a * t.
V – V0 = a * t.
t = (V – V0) / a = (20 – 5) / 0.75 = 20 s.
Answer: It will take 20 seconds to increase the machine speed from 5 m / s to 20 m / s.
