Question

The fastest commercially available rifle bullet claims a muzzle velocity of 4225 ft>s. (a) what is this speed in miles per hour

Answer 1

Answer : 2880.68274  miles/hour

1 foot = 0.000189394 miles

4225 feet = 0.000189394* 4225 miles

distance traveled in 1 second =   0.000189394* 4225 miles

distance traveled in 1/3600 hours =   0.000189394* 4225 miles

distance traveled in 1 hour =   0.000189394* 4225 * 3600 miles

Speed is = 2880.68274 miles/hour
