A rope passes over a fixed sheave with both ends hanging straight down. The coefficient of friction between the rope and sheave
Oliga [24]

Answer:3.51

Explanation:

Given

Coefficient of Friction \mu =0.4

Consider a small element at an angle \theta having an angle of d\theta

Normal Force=T\times \frac{d\theta }{2}+(T+dT)\cdot \frac{d\theta }{2}

N=T\cdot d\theta

Friction f=\mu \times Normal\ Reaction

f=\mu \cdot N

and T+dT-T=f=\mu Td\theta

dT=\mu Td\theta

\frac{dT}{T}=\mu d\theta

\int_{T_2}^{T_1}\frac{dT}{T}=\int_{0}^{\pi }\mu d\theta

\frac{T_2}{T_1}=e^{\mu \pi}

\frac{T_2}{T_1}=e^{0.4\times \pi }

\frac{T_2}{T_1}==e^{1.256}

\frac{T_2}{T_1}=3.51

You are on a skateboard not moving when your friend throws you a basketball and you catch it. The 0.50kg basketball was going 5
Sidana [21]

Answer:

a. Your mass with the basketball is 55.5 kg

b. Your new velocity is 0.045 m/s

Explanation:

We first add your weight and the basketballs weight to get 55.5 kg.

Then to find b. we use the equation: v final = (m1 * v1) / (m1 +m2)

So m1 is the basketball which is 0.5 kg and v1 is 5 m/s. So the top half is (0.5 * 5)

The bottom half is just our weights added together.
