Elephants can run about 25 mph. This equates to 36.6667 feet per second.
Multiply feet per second by 0.3048 to get meters per second.
Jesse is traveling at 154 feet per second.
To convert miles per hour to feet per second multiply by 5280 (feet in a mile) and then divide by 3600 (seconds in an hour).
8.8 feet per second.
The speed of light is 983,571,056 feet per second.
80.67 feet per second.
10 mph = 14.6 feet per second.
"Per second per second" is a measurement of acceleration. If an object (such as a car) is moving, its speed can be measured in terms of miles per hour, or feet per second (which work out to be a similar figure to miles per hour). If the car is accelerating, the acceleration can be measured in terms of additional speed (feet per second) that is acquired in a given second, therefore, feet per second per second. Get it?
Speed or velocity can be measured in a number of units. Miles per hour, feet per second, metre per second.
Its speed is 6 feet per second. Its velocity is 6 feet per second in whatever direction it's going.
The earth rotates at about 1,038 mph at the equator. This equates to 1,522.4 feet per second.
It can't be done. 20 feet per second per second is acceleration, but mph is a speed.
