A car accelerates at a rate of 0.6 m/s2. How long does it take for this car to go from a speed of 55 mi/h to 60 mi/h?
I wonder about the school subject college? Is there such a course?
a= deltaV/time
solve for time. I recommend changing mi/hr to m/s
Physical science
seriously? you need help with that?
To find the time it takes for the car to accelerate from 55 mi/h to 60 mi/h, we need to follow these steps:
Step 1: Convert the speeds from miles per hour to meters per second:
- 55 mi/h = (55 * 1609.34) / 3600 m/s ≈ 24.59 m/s
- 60 mi/h = (60 * 1609.34) / 3600 m/s ≈ 26.82 m/s
Step 2: Calculate the change in velocity:
- Change in velocity = Final velocity - Initial velocity = 26.82 m/s - 24.59 m/s = 2.23 m/s
Step 3: Determine the acceleration in meters per second squared (m/s2):
- Given acceleration = 0.6 m/s2
Step 4: Use the equation of motion to calculate the time taken:
- Time = Change in velocity / Acceleration
- Time = 2.23 m/s / 0.6 m/s2 ≈ 3.72 seconds
Therefore, it takes approximately 3.72 seconds for the car to go from a speed of 55 mi/h to 60 mi/h.
