A medicine ball (also called an exercise ball, or a health ball) is a weighted ball about the shoulder diameter (approx. 13.7 inches), often used for recovery and strength training.... In 1705 similar large balls had been used in Persia.So you can use your medicine ball as a projectile to boost the strength of your throws.

You have developed a method in which a paint shaker is used to measure the coefficient of static friction between various object
Paladinen [302]

Answer:

0.62

Explanation:

A = Amplitude

f = Frequency = 1.85 Hz

\mu = Coefficient of static

g = Acceleration due to gravity = 9.81 m/s²

Angular frequency

\omega=2\pi f\\\Rightarrow \omega=2\pi\times 1.85

Maximum acceleration

a_{max}=A\omega^2\\\Rightarrow a_{max}=0.045\times (2\pi\times 1.85)^2

a_{max}=\mu g\\\Rightarrow \mu=\frac{a_{max}}{g}\\\Rightarrow \mu=\frac{0.045\times (2\pi\times 1.85)^2}{9.81}\\\Rightarrow \mu=0.62

Coefficient of static friction between penny and tabletop is 0.62
