Did you know?
Did you know that the acceleration of a car is a measure of how quickly its velocity is changing? For instance, if a car has an acceleration of 2.4m/s square, it means that every second its velocity increases by 2.4 meters per second.
Now, here's an interesting question to ponder: Starting from rest, how long does the car require to reach a velocity of 90km/h? To find the answer, we need to convert the final velocity to meters per second (since acceleration is given in m/s square). So, 90km/h is equivalent to 25m/s.
Next, we can use the formula: velocity = initial velocity + (acceleration x time) to solve for time. Since the car starts from rest, the initial velocity is 0. Rearranging the formula, we have: time = (final velocity - initial velocity) / acceleration.
Substituting the given values, we get: time = (25m/s - 0) / 2.4m/s square. After doing some calculations, we find that the car requires approximately 10.42 seconds to reach a velocity of 90km/h.
Here's another interesting fact: while the car is accelerating, it also covers a certain distance. To determine how far the car travels while reaching that velocity, we can use the formula: distance = (initial velocity x time) + (0.5 x acceleration x time square). Since the initial velocity is 0 and the time is 10.42 seconds, we can simplify the formula to: distance = 0.5 x acceleration x time square.
Substituting the given values and solving the equation, we find that the car travels approximately 132.68 meters while reaching a velocity of 90km/h.
So, did you know that a car with an acceleration of 2.4m/s square takes around 10.42 seconds to reach a velocity of 90km/h? Additionally, it covers a distance of approximately 132.68 meters during that time. Acceleration is truly fascinating when considering a car's speed and distance traveled!
