Question
Transcribed Image Text:A block of mass \( m \) begins at rest at the top of a ramp at elevation \( h \) with whatever potential energy (PE) is associated with that height.
The block slides down the ramp over a distance \( d \) until it reaches the bottom of the ramp. How much of its original total energy (in joules) survives as kinetic energy (KE) when it reaches the ground?
(In other words, the acceleration is not zero like it was in lab and friction does not remove 100% of the original potential energy. How much of that original energy is left over after the friction does work to remove some?)
- \( m = 4.9 \, \text{kg} \)
- \( h = 5.4 \, \text{m} \)
- \( d = 5 \, \text{m} \)
- \( \mu = 0.3 \)
- \( \theta = 36.87^\circ \)
**Diagram Explanation:**
The diagram shows a block on a ramp inclined at an angle \( \theta \). The block experiences forces including gravitational force (\( mg \)) and frictional force (\( F_r \)). The height of the ramp is \( h \), and the distance along the ramp is \( d \).
