Question

The engine of a sports car rotates at 5,000 revolutions per minute (rpm). Calculate the angular speed of the engine in radians per second. Use 2(pi) radians = 1 revolution

Answer 1

523.6 radians per second

Answer 2

can you show how....

Answer 3

this is new to me

Answer 4

never done trig before

Answer 5

5000 rpm = (5000 / 60) = 83 and 1/3 rev per second.
IF (and that's a big IF) each rev = 2 radians, then the angular speed is (83 and 1/3) x 2 = 166 and 2/3 rad/sec.

But wait ! Don't go away. That's a bogus answer.

We cannot allow a sterling example of our fine work here at Wiki.Answers to go out with the claim that 1 revolution is the same as 2 radians. It's not !

1 revolution = 2 pi radians

The true angular speed of that engine is (83 and 1/3) times (2 pi) = 523.6 radians per second (rounded)

Answer 6

lol, thts a problem with most college ppl.
nvm, we will work thorugh it.
