Question

suppose you are pushing a friend in a wheelchair up a ramp. which ramp should be used if you want to use the least amount of force? select one: a b c d

Explanation:

Step1: Understand the principle

The force required to push an object up a ramp is related to the ramp's slope. The smaller the slope, the less force is needed.

Step2: Analyze the ramps

The slope of a ramp is determined by its height - to - length ratio. Among the given ramps, the ramp with the least steepness (longest base relative to height) will require the least force. Ramp D has the longest base for a given height compared to A, B, and C.

Answer:

D
