Choose the correct pair of action / reaction forces. Assume the car is moving forward. O tire pushes roadway back roadway pushes tire forward O tire pushes roadway down O roadway pulls tire down O roadway pushes tire back

Below are eight crates of different mass. (Figure 1) The crates are attached to massless ropes, as indicated in the picture, where the ropes are marked by letters. Each crate is being pulled to the right at the same constant speed. The coefficient of kinetic friction between each crate and the surface on which it slides is the same for all eight crates. igure 1 kg 3 kg с F 2 kg 2 kg B 3 kg E D ………………1 kg …………………..mm 3 kg A 5 kg G H 1 of 1 Rank the ropes on the basis of the force each exerts on the crate immediately to its left. Rank from largest to smallest. To rank items as equivalent, overlap them. ► View Available Hint(s) largest The correct ranking cannot be determined.

You sit behind the wheel of your car on level ground, release the brake, put the gearshift in neutral, and push as hard as you can against the steering wheel of the car. Why doesn't the car move forward?

Two blocks are positioned on surfaces, each inclined at the same angle of 44.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 5.58 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?     13.04 kg     5.79 kg     8.69 kg     4.08 kg
