Slanted surfaces with friction: A 250-kg crate is on a rough ramp, inclined at 30° above the horizontal. The coefficient of kinetic friction between the crate and ramp is 0.22. A horizontal force of 5000 N is applied to the crate, pushing it up the ramp. What is the acceleration of the crate? A) 8.4 m/s² B) 10 m/s² C) 12 m/s² D) 13 m/s² E) 3.4 m/s²

Question

Quizplus · Accepted Answer

The correct answer is A because the acceleration of the crate is 8.4 m/s2. This can be calculated using the formula a = (F - f) / m, where F is the applied force, f is the force of friction, and m is the mass of the crate.
