413,000 weight car starts at rest and rolls down a hill from height of 10.0, then moves across level surface collides with light spring-loaded guardrail. Neglecting friction, what is the maximum distance the spring is compressed? The spring constant = 10 N/m. Calculate the maximum acceleration of the car after contact with the spring, again neglecting friction. If the spring only compressed 0.30 m, find the force exerted by the spring. If the spring entirely lost through friction, predict the velocity following the path. Use time and acceleration time graph to answer the following questions: Identify the path which represents uniform motion. Identify the path which represents accelerating motion. Identify the path which represents being at rest. A 0.326 kg bead slides on a curved wire, starting from rest at point 4 in the given figure. The acceleration due to gravity is 9.8 m/s^2. Using conservation of energy, assuming the wire is frictionless, find the speed of the bead at point M. A roller coaster cart of mass 298 kg starts from a stationary point where the height is 273 m and while later where the height is 146 m. The acceleration due to gravity is 9.8 m/s^2. What is the percent of the cart's relative ground potential energy, ignoring the effect of friction? What is the speed of the cart at the later point? Use conservation of energy. Two packing crates with masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley. The 5.00 kg crate lies smoothly on an incline of 40.0 degrees. Find the acceleration of the 5.00 kg crate. Calculate the tension in each string. Is the tension in each string approximately equal to each other?
