Question 896807: If you use a spray-on deodorant, you can find out how fast it comes out of the can if you know the relative pressure inside the can. Supposing a full can of deodorant has an exit velocity(v) of 42 feet per second,use the formula below to find the relative pressure inside the can (p) in psi (pounds per square inch)
v= 7√p

Any help and step by step instructions would be awesome :-)
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
42 = 7 * square root of p
square both sides of =
1764 = 49p
p = 1764 / 49 = 36
pressure inside can is 36 pounds per square inch
