Sketch a free-body diagram (i.e., a force diagram) for each object. A person pulls with 55N of force on a light-weight cord attached to a 10kg box. The cord makes a 30° angle above the horizontal. The coefficient of kinetic friction between the surface and box is 0.25.Determine the acceleration of the box. ΣΕx: X' ΣF₁: a₁ = X 30⁰ m/s²

Sketch a free-body diagram (i.e., a force diagram) for each object. A hand applies a14N force at an angle of 30° to the horizontal to a 4kg block sliding along a floor. The coefficient of kinetic friction between the block and the floor is 0.1. Find the acceleration of the block. ΣF.: ΣΕ: 14N 30° a¸ = X k=0.1 4kg m/s²

4.15 in Lab 7 Sketch a free-body diagram (i.e., a force diagram) for each object. A hand applies a 10N force at an angle of 20° to the horizontal to a 2kg block sliding against a wall. The coefficient of kinetic friction between the block and the wall is 0.1. Assume the block starts from rest. Determine whether the block slides up or down the wall. Find the acceleration of the block. ΣΕ: ΣΕ: 10N 20° a = ₁0.1 2kg 2 m/s²
