Final answer:
The car traveling at 4.40 m/s corresponds to 9.68 miles per hour. Additionally, a car accelerating at 1.40 m/s² takes approximately 1.43 seconds to reach a speed of 2.00 m/s from rest.
Step-by-step explanation:
Speed Conversion and Motion
Let's start with converting the given speed of the car from meters per second to miles per hour. Knowing that 1 meter per second is approximately 2.2 miles per hour, we can simply multiply the given speed by this conversion factor.
Conversion:
4.40 m/s * 2.2 mi/h per 1 m/s = 9.68 miles per hour.
To address another problem from the reference questions, a car that accelerates at 1.40 m/s² will reach a speed of 2.00 m/s based on the formula v = u + at, where v is the final velocity, u is the initial velocity (0 m/s, since the car starts from rest), a is the acceleration, and t is the time in seconds.
2.00 m/s = 0 + (1.40 m/s² * t)
Solving for t gives:
t = 2.00 m/s / 1.40 m/s² = 1.43 seconds (to two decimal places).
