%3DA cart of mass M = 0.7 kg is attached to a spring with force constant k = 3 N/mrespect to the horizontal. With the spring in the unstretched position, the cart isreleased from rest at an initial height of unknown value. What is the maximumand suspended on a frictionless inclined plane that makes a 20° angle withextension of the spring,Axmax,when the cart is at its lowest point on the inclineтах»(i.e. when the velocity of the car is reduced to zero again after being released)?Hint 1: Write down conservation of mechanical energy for the cart. Don't worryif your expression involves variables that is are not given.Hint 2: How does the height difference hf – h; of the cart relate to theextension of the spring, Ax?-K4xM20°

Solution: Let us write the conservation of mechanical energy for the initial and final positions.…

You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 10-m-high hill, then descends 17 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5 m and that a loaded car will have a maximum mass of 400 kg. For safety reasons, the spring constant should be 13% larger than the minimum needed for the car to just make it over the top. k = 1.4x104 Submit Part B m Previous Answers Correct Correct answer is shown.

A certain spring is found not to obey Hooke's law; it exerts a restoring force F(x) = -ax² - 6x³ if it is stretched or compressed, where: a = 10.0N/m², B = 300.0N/m³ The mass of the spring is negligible. Calculate the potential energy function U(x) for this spring, if U(x=0) = 0. Find the spring potential energy at x = 0.500 m

A box with 14 kg of mass slides down an inclined plane that is 1.8 m high and 3.9 m along the inclined plane. Due to friction the box reaches 4.6 m/s at the bottom of the inclined plane. Beyond the inclined plane lies a spring with 750 N/m constant. It is fixed at its right end. The level ground between the incline and the spring has no friction When the box is temporarily stopped by the spring, how much is the spring compressed in m? Hint: start from the bottom of the inclined plane since you know the speed of the box there. Not all values must be used.
