9.81 meters per second = 32.18 feet per second.
60 feet per second is 65.84 km/h
4 meters per second equates to 787.4 ft/min
75 km per second = 14,763,779.5 feet per minute.
take the inches and divide them by 12 then take the seconds and divide them by 60 then you will have sucessfully converted inches per second to feet per minute. 120inces =10 ft 180 sec= 3 min therefore you r object is traveling at 3.3333 ft. per sec.
Without knowing what this needs to be converted to, here we go... 18.5 miles per second is equal to: 66,600 mph 106,217 kmh 57,352 kts 29,505 m/s 96,800 ft/s 5,808,000 ft/min 0.0000992457291 lightyears per year
That works out to a speed of exactly 60 feet per second.It can also be converted to roughly 40.92 miles per hour, or 109,963.6 furlongs per fortnight.
So what does acceleration mean. Let's break it down. It is a gain of speed. Your speed here is in ft per second. Now think of it as a gain of 32ft per second with every second that passes. I.e. Something at rest, after 1 second it will be going 32ft per sec. After 2 secs it will be going 64 ft per second and so on.
About 0.6 ft per second.
The initial velocity of the ball thrown upward at 16 ft per second is 16 ft/s.
32.1740 ft/s^232.174 ft per second2
30 inches per second at 150 feet per minute.
170 miles = 170*5280 = 897,600 feet. So 170 mph = 879,600 ft per hour.
