Sample Problem and Detailed Solution from SolutionBank
Let’s illustrate problem-solving with an example:
Problem:
A solid sphere of mass 2 kg and radius 0.5 m rolls down an inclined plane of length 4 m inclined at 30°. Find the velocity of the sphere at the bottom, assuming no slipping and frictionless rolling.
Solution Steps:
- Identify knowns:
- Mass, m = 2 kg
- Radius, R = 0.5 m
- Incline length, s = 4 m
- Incline angle, θ = 30°
- Calculate initial potential energy:
\[
PE_{initial} = mgh
\]
where \( h = s \sin \theta = 4 \times \sin 30° = 4 \times 0.5 = 2\, \text{m} \).
\[
PE_{initial} = 2 \times 9.8 \times 2 = 39.2\, \text{J}
\]
- Apply conservation of energy:
\[
KE_{bottom} + PE_{bottom} = PE_{initial}
\]
At the bottom, \( PE = 0 \), so:
\[
KE_{bottom} = 39.2\, \text{J}
\]
- Moment of inertia for solid sphere:
\[
I = \frac{2}{5} m R^2
\]
The rotational kinetic energy:
\[
KE_{rot} = \frac{1}{2} I \omega^2
\]
The translational kinetic energy:
\[
KE_{trans} = \frac{1}{2} m v^2
\]
and the relation between \( v \) and \( \omega \):
\[
v = \omega R
\]
- Express total kinetic energy:
\[
KE_{total} = KE_{trans} + KE_{rot} = \frac{1}{2} m v^2 + \frac{1}{2} \times \frac{2}{5} m R^2 \times \left(\frac{v}{R}\right)^2 = \frac{1}{2} m v^2 + \frac{1}{5} m v^2 = \frac{7}{10} m v^2
\]
- Solve for \( v \):
\[
\frac{7}{10} m v^2 = 39.2
\]
\[
v^2 = \frac{39.2 \times 10}{7 \times 2} = \frac{392}{14} = 28
\]
\[
v = \sqrt{28} \approx 5.29\, \text{m/s}
\]
- Final Answer: The velocity of the sphere at the bottom is approximately 5.29 m/s.
