3. a bicycle of wheel radius 1.3 m undergoes 25 rotations in 60 s. determine a) the frequency of rotation. (remember, frequency is the number of cycles per unit time)

3. a bicycle of wheel radius 1.3 m undergoes 25 rotations in 60 s. determine a) the frequency of rotation. (remember, frequency is the number of cycles per unit time)

Answer

Explanation:

Step1: Identify given values

Number of rotations $n = 25$, time $t=60\ s$

Step2: Apply frequency formula

Frequency $f=\frac{n}{t}$ Substitute $n = 25$ and $t = 60\ s$ into the formula: $f=\frac{25}{60}=\frac{5}{12}\ Hz\approx0.42\ Hz$

Answer:

$\frac{5}{12}\ Hz\approx0.42\ Hz$
