Question

Newton's Laws and Their Applications What average force is required to accelerate a 5 kg block from rest to a final speed of 54 m/s in 9 s? A 1500 kg car moving at a speed of 45 mph comes to a stop after traveling a distance of 200 m. What was the average force exerted by the brakes on the car? A horizontal force of 150 N is applied to a 20 kg box, which causes it to move to the right. (a) What is the acceleration if there is no friction? (b) What is the acceleration if the coefficient of kinetic friction is 0.25? (c) Using the acceleration, what is the final speed of the box after 8 seconds? A rope lifts up a 5 kg box with a tension force of 80 N. What is the acceleration of the box? A 10 kg box rests at a 30-degree incline and begins to slide down. (a) What is the acceleration if no friction is present? (b) What is the acceleration if the coefficient of kinetic friction is 0.20? (c) What is the final speed of the box when it reaches the bottom of an inclined plane that is 200 m? (Use the answer in part b)
