This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the

In the situation shown in image, let u be the angle of the slope and suppose there is friction between the cart and the track. You find that if the cart and bucket each have the same weight w, they remain at rest when released. In this case, what is the magnitude of the friction force on the cart? Is it less than, greater than, or equal to w?
A crate of 68 kg simply stands on the moving cart with constant acceleration a. The height from the center of gravity to the cart, L, is 1.5 m, and the angle 0= 13°. What is the maximum acceleration a (in m/s²) the cart can have without tipping over on the cart? The coefficient of static friction between the crate and the cart is ls = 0.49.

Required information A photograph of the NASA Apollo 16 Lunar Module (abbreviated by NASA as the LM) is shown on the surface of the Moon. Such spacecraft made six Moon landings during 1969 - 72. A simplified model for one of the four landing gear assemblies of the LM is shown. Assume the weight of the LM is uniformly supported by all four landing gear assemblies, and neglect friction between the landing gear and the surface of the Moon. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

This is an example diagram of Atwood’s Machine. This machine works by hanging two masses on a pulley, with each mass being acted upon by gravity. Since the masses are on opposite sides of the pulley, their weights oppose each other, and the net acceleration is less than g. To see this, please draw in all of the relevant forces in the diagram below. Be sure to indicate which direction friction in the pulley is acting. Assume m1 > m2.

Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)
