Question

precalc

Answer 1

the rad/sec part

Answer 2

and I got about 75.864 RPM, can someone check that?

Answer 3

1 radian corresponds to the length of the radius, so it's just dividing 65mph by 12inches right?

Answer 4

And then converting that to /sec instead of /hour

Answer 5

Oh do you want me to check your answer

Answer 6

65 miles/hour divided by 12 inches is 343200 radians/hour

Answer 7

which is 343200 radians/3600 seconds so do the math

Answer 8

basically the length of the circumference equal to the radius of a circle corresponds to an angle of 1 radian, that's how it's defined

Answer 9

np, that was a good question

Answer 10

so i got 286/3 rad/sec

Answer 11

what about Rounds per minute?

Answer 12

this is what I did: 65mph = 5720 in/min
5270in/min)/(24pi in/rev) = about 75.864 RPM
