QUESTION:
Problem 46GP
A Porsche sports car can accelerate at 14m/s2, (a) Is this acceleration greater than, less than, or equal to 14 ft/s2? Explain, (b) Determine the acceleration of a Forsche in ft/s2.
(c) Determine its acceleration in km/h2.
ANSWER:
Step 1 of 3
Part a
We are required to check if 14 m/s2 is greater than 14 ft/s2 or not.
1 metre = 3.28 feet
14 meters = 45.93 feet
So, the acceleration 14 m/s2 in ft/s2 is 45.93 ft/s2. This is greater than 14 m/s2.
