Answer:
v = 7.54m/s
Explanation:
Okay, so we can first start of by finding the period. The equation for period is:
T = seconds / cycle. WE know in 9.37s, it does 25 revolutions (cycles), so we can find the period:
T = seconds / cycle
T = 9.37s / 25
0.3748 = T. We will use this as our time.
We then need to find the velocity, so we use the formula for velocity:
v = d/t. But d is the circumferance as its circular motion (circle).
so circumferance is 2πr. We know everything, and now we solve for velocity:
v = d/t
v = 2πr / t
v = 2π*0.450 / 0.3748
v = 7.54m/s
