5. A 750g cart is attached to a spring, and hung down the side of an incline plane, as shown below. The spring constant is 765.5 N/m, and the angle of incline is 25 degrees. Determine the length the spring will stretch to when settled into equilibrium. le start end

The equation which related stress o to strain e is similar to: a. Newton's second law F = ma b. Hooke's law for springs F = kAx С. Newton's law of gravitation O d. A object being acted on by gravity. F = mg
