##### Reference no: EM13544213

A spring is mounted at angle of 35 degrees on a frictionless incline. The spring is compressed by 15 cm where it is allowed to propel a mass of 5.5 kg up the incline. a. if the spring constant is 550 N/m, how fast is the mass moving when it leaves the spring? b. To what maximum distance from the starting point will the mass rise up the incline?
