- A man is pulling a 25 kg wagon forward at some unknown acceleration. Assuming he is pulling the wagon 178N forward with a rope that is found 29o above the horizontal, and the coefficient of friction between the wagon and the ground is 0.300: a) Determine the acceleration of the wagon. b) Would the acceleration of the wagon change if you pushed the wagon at the same angle rather than pulled it?

Problem 4) A tesla model X electric vehicle is driving from Boston to Lenox on 195, on a straight section of the highway, no traffic and perfect weather at 70 miles/per hour. It has a perfectly constant speed. Can you say it has no forces acting on it since there is no acceleration?(equal magnitude) A В D E This car is going through a "loop-the-loop" at constant speed. Assume sufficient speed to remain on the track, and ignore air resistance and friction. Which is the correct free body diagram of the car, at the moment shown? O A O B O C O D O E
- Two forces, F1 and F2 (which is directed in the -x-direction), act on a 5.00-kg block as shown. The block slides horizontally. The magnitude of the forces are F1 = 50.0 N and F2 = 35.0 N. What is the horizontal acceleration (both magnitude and direction) of the block?
