Solved in 4 steps with 4 images
- How would you figure this out??We did a lab for physics class and the setup is like the image. the second image is force, acceleration, position-time graphs from a software The cart's mass: 0.774kg the hanging mass: 0.070 kg distance travelled by the hanging mass: 0.7455 m Question: Part 1: Calculate the work done by the hanging mass. Part 2: Do the answers to part 1 support the work-energy theorem? Offer reasons why there might be a small difference?Need help with a physics problem, image included. Thanks!

A 5 kg ball is swinging back and forth on a string as shown. You may make the following assumptions: A is the highest point in the swing. The speed of the ball is 4.3 m/s at point B., and at this point it is at "ground level" The ball is 0.3 m above the "ground" at point C A B KE PE V 4.3 m/s A Footer Different first page OptionsAssume each car with its occupant has a mass of 200 kg. Calculate G, H, and I. Show all of your work.
- You stand on the top of a tall building and throw a baseball directly downwards. When the baseball leaves your hand, it has a speed of 6 m/s. (Assume there is no air resistance for this problem) a. Four seconds after you throw it, what is the acceleration of the baseball? Show your work and explain your steps. b. Four seconds after you throw it, what is the velocity of the baseball? Show your work and explain your steps.Please solve question 1, 2 and 3 ASAP I really need helpYOU MUST ONLY USE ENERGY CONCEPTS TO COMPLETE THE PROBLEMS BELOW. 1. A toy truck with a mass of 78g is travelling at 15.5m/s on a rough surface. If the car is subject to a friction force of 25N, how far will it travel while slowing down to a speed of 2.5 m/s?
- Two objects of different mass start from rest and are pulled horizontally with negligible friction by the same magnitude net force and moved through the same distance. The work done on object 1 is 4000 joules. After the force has pulled each object, object 1 is seen to move with half the speed of object 2. Answer the following questions and show your work. a. How much work is done on object 2? b. What is the kinetic energy of object 1 after being pulled? Explain. C. What is the kinetic energy of object 2 after being pulled? Explain. d. What is the ratio of the mass of object 1 to the mass of object 2? Explain and show work.A football punter wants to kick the ball so that it is in the air for 4.0 s and lands 50 m from where it was kicked. a. Skecth the path of the football showing horizontal and vertical components of velocity throught it's path on the same diagram. Label all important parameters in the diagram. b. At what angle and with what initial speed should he kick the ball? Assume the ball leaves 1.0 m above the ground. Show all work neatly. Posted Today at 8:48 pm10. Ā = -2â + -3ŷ and B = -4â + -4ŷ.
