•• Your roommate is working on his bicycle and has the bike upside down. He spins the 60-cm-diameter wheel, and you notice that
Y_Kistochka [10]

Answer:

v=0.57\frac{m}{s}

a_c=10.83\frac{m}{s^2}

Explanation:

We have an uniform circular motion, therefore, the pebble’s speed is given by the distance traveled in a revolution (2\pi r) and the period (T), since this is the time pebble’s takes to complete a revolution:

v=\frac{2\pi r}{T}

The period is inversely proportional to the frequency:

T=\frac{1}{f}

So, we have:

v=\frac{2\pi r}{\frac{1}{f}}\\v=2\pi rf\\

Recall that the radius is the half of the diameter and one revolution per is equal to one Hz:

v=2\pi (30*10^{-2}m)(3Hz)\\v=0.57\frac{m}{s}

The centripetal acceleration is defined as:

a_c=\frac{v^2}{r}\\a_c=\frac{(0.57\frac{m}{s})^2}{30*10^{-2}m}\\\\a_c=10.83\frac{m}{s^2}

hockey puck slides across the ice with an initial velocity of 7.2 m/s. It has a deceleration of 1.1 m/s2 and is traveling toward
dimulka [17.4K]

For this use the formula:

d = Vo * t - (at^2) / 2

Clearing t:

t = d/(v + 0.5*a)

Replacing:

t = 5 m / (7.2 m/s + 0.5 * (-1.1 m/s²)

Resolving:

t = 5 m / (7.2 m/s + (-0.55 m/s²)

t = 5 m / 6.65 m/s

t = 0.75 s

Result:

The time will be <u>0.75 seconds.</u>
