Problem 1: A package is released down on a ramp from the height hı, slides down and compresses the string by an amount d at the end of the ramp. Once the spring bounces back the package is pushed back on the ramp and travels up on the ramp until it momentarily stops at distance lz from the compressed position of the spring. If the coefficient of friction u = 0.3, angle a = 30°, spring deflection d = 0.1 m and length of the ramp package travels l; = 2.5 m, determine the height h2 the package will reach after it bounces back. Solve the problem using the principle of Conservation of Energy
