Q. A spring is mounted at an angle of theta = 34degrees on a frictionless incline as illustrated in the figure below. The spring is compressed to 15 cm where it is allowed to propel a mass of 5 kg up the incline. (a) If the spring constant is 560 N/m, how fast is the mass moving when leaves the spring? (b) To what maximum distance from the starting point will the mass rise up the incline?
