Just question A

Class Period 29: Energy Conservation Practice D3 Don't forget to draw a picture! 14 Will include identifying an initial and hind state. To The thing you're looking for should be at either you initial or final state BE We = AKE + APE ( EkXP - EKX 2 ) for each spring W= Fx d cas $ x ( maye - may. ) for each object in System ( 2 mup - 2mv:2 ) for each object in the system Symbolic first ! ( Some things might cancel )A block of mass m is placed against a spring with spring constant k, which lies parallel to an incline that makes an angle & with respect to the horizontal. The spring is compressed a distance s, where the block is level with the ground on either side of the incline. When the block is released, it slides up the incline. The coefficient of kinetic friction between the block and the incline is pup.. The block travels a distance _ until it reaches the top of the incline. It then travels under the influence of gravity alone until striking the ground. L X Given the following values for the the variables referenced in the problem: m = 2.86 kg k = 52,360 N/m s = 4.21 cm 0 = 22.4 degrees L = 119.9 cm HK = 0.299 Determine the following: (a) The speed of the block at the top of the incline. "top Number Units (b) The speed of the block when it impacts the ground after leaving the incline. "hit Number Units (c) The distance from the incline where the block hits the ground (I in the diagram)- I Number Units
