In the diagram below a car starts from rest at point A. It then slides down the hill, travels around the loop (the loop's diameter is 62 m). When the ca minimum possible speed it could be going without falling. After completing the loop, it compresses a 1,519,000 N/m spring 4.8 m. Assume there's no A.) Determine how high point A is above point C. 15.5 m B.) Determine the car's mass. 11520 kg x x

7. The cart, in the diagram below, travels .80 m down the ramp with uniform acceleration in 1.5 seconds. The initial velocity(v.) is 0 m/s. You must show work. Determine the following. If answer requires a calculation, you must show work. The initial velocity(v.) is 0 m/s. a. Average Velocity b. Acceleration c. The dots in the strips below represent the position of the cart as it rolls down the .80- meter-long ramp. The time intervals between the dots are equal. Which of the strips best represents the motion of the cart down the ramp? Justify your choice. d. Which two strips represent an object moving at constant velocity? Justify your answer.

Can you please answer this question and show all of the steps

I need help with hw problem #3 please.

Three objects with masses m, = 4.8 kg, m, = 14 kg, and m, = 17 kg, respectively, are attached by strings over frictionless pulleys as indicated in the figure below. The horizontal surface exerts a force of friction of 30 N on m,. If the system is released from rest, use energy concepts to find the speed of ma after it moves down 4.0 m. 5.1 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s

Label the formula used. Explain and show the complete solution.

need assistance please  1. If a spring has a spring constant k = 24 N/m, how far would you have to stretch the spring to store 55 Joules of potential energy

solve question 3 pleaseeee

Please show your work, thank you :)
