- I have a question for elevator problems: Newton's law states that there is always an equal and opposite force. But for elevator problems, if it accelerates upwards... we say that the normal force is greater than the gravitational force. So is Newton's third law still applied here and if so how? Because technically the opposite force is not equal in magnitude for it to be able to accelerateMass (kg): Top Speed (m/s): Distance (m):U) Wildl iS tne timuSt TUrte Ul the nuciedi engine III NEWLUIS? 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?

I have tried the options many of times but can't figure out where I am wrong. For the most part it can't be too many forces acting on the player. The multi-choice options were: Weight Tension Force Kinetic Friction Force Normal Force I have chosed Normal Force and Weight as my top two. But somehow i'm still wrong or missing something.
- A 7 kg mass is placed on a table with Ms= 0.18 and Mk= 0.15. How much mass must be suspended on m in order to start the 5 kg moving? What is the resulting acceleration? This is basically the situation we set up in Lab several times…... a pulley system is placed such that the weight of mass 2 will pull horizontally to the table the 7 kg is placed upon.A 60 kg skydiver falls, beginning at rest. This isn't an ordinary skydive though, because it's taking place on an alien planet where g = 8 m/s2. The drag force on the skydiver is given by FD = -0.14 v (N). Calculate the speed of the skydiver after they have fallen for 322 s, in m/s. (Please answer to the fourth decimal place - i.e 14.3225)A person stands on a scale inside an elevator at rest. The scale reads 800 N. The elevator accelerates downward at the rate of 2.4 m/s ^ 2 . What does the scale read then? Calculate answer to one decimal. (use g = 9.8 m/s ^ 2 )
- Two masses, pulley, incline with friction: Two blocks of mass M and m are connected by a light rope that passes over a frictionless pulley. The mass M moves down the incline, which has an angle of inclination, as shown. The coefficient of kinetic friction between M and the incline is μ. (See PSL 5.5,7,9) a) Draw FBDs for each mass. b) In terms of the given symbols and any known constants (like g), solve for (i) the tension in the rope, and (ii) the acceleration. c) If M = 10.0 kg, m = 7.00 kg, μ = 0.200, 0 = 30.0°, what are the values of the tension and acceleration? ImThe harder you hit the brakes while driving forward, the more the front end of your car will move down (and the rear end move up). Why? What happens when cars accelerate forward?
