A solid ball of mass M = 2.0 kg and radius R = 0.25 m starts from rest at a height h = 3.0 m above the bottom of the path. It ro
Lady bird [3.3K]

Answer:

6.48 m/s

Explanation:

We are given that

Mass,M=2 kg

Radius,R=0.25 m

Height,h=3 m

Moment of inertia of solid sphere=I=\frac{2}{5}MR^2

We have to find the linear speed.

\omega=\frac{v}{R}

By law of conservation of energy

mgh=\frac{1}{2}I\omega^2+\frac{1}{2}mv^2

mgh=\frac{1}{2}I(\frac{v}{R})^2+\frac{1}{2}mv^2=\frac{1}{2}v^2(\frac{I}{R^2}+m)

Where g=9.8m/s^2

Substitute the values

2\times 9.8\times 3=\frac{1}{2}(\frac{2}{5R^2}MR^2+M)=\frac{7}{10}Mv^2=\frac{7}{10}(2)v^2

v^2=\frac{2\times 9.8\times 3\times 10}{7\times 2}

v=\sqrt{\frac{2\times 9.8\times 3\times 5}{7}}

v=6.48m/s

The acceleration due to gravity on Earth is 9.80 m/s2. If the mass of a honeybee is 0.000100 kilograms, what is the weight of th
Yuliya22 [10]

Answer:

0.00098 N

Explanation:

The weight of an object is given by:

W=mg

where

m is the mass of the object

g is the gravitational acceleration on the planet

In this problem, we have:

m=0.0001 kg is the mass of the honeybee

g=9.8 m/s^2 is the acceleration due to gravity

Substituting into the equation, we find:

W=mg=(0.0001 kg)(9.8 m/s^2)=0.00098 N
