# A block is released from rest and slides down a frictionless ramp inclined at [katex] 30^\circ [/katex] from the horizontal. When the block reaches the bottom, the block-Earth system has mechanical energy [katex] \text{E}_i [/katex]. The experiment is repeated, but now horizontal and vertical forces of magnitude [katex] F [/katex] are exerted on the block while it slides, as shown above. When the block reaches the bottom, the mechanical energy of the block-Earth system

A block is released from rest and slides down a frictionless ramp inclined at  \( 30^\circ \) from the horizontal. When the block reaches the bottom, the block-Earth system has mechanical energy \( \text{E}_i \). The experiment is repeated, but now horizontal and vertical forces of magnitude \( F \) are exerted on the block while it slides, as shown above. When the block reaches the bottom, the mechanical energy of the block-Earth system.

- **A.** is greater than \( \text{E}_i \)
- **B.** is equal to \( \text{E}_i \)
- **C.** is less than \( \text{E}_i \)
- **D.** cannot be determined without knowing \( F \)
