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?
A block with mass m1 = 9.4 kg is on an incline with an angle ? = 24.0° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: ?k = 0.23 and ?s = 0.253. 1) When t..
