A 5 kgblock is placed near the top of a frictionless ramp, which makes an angle of30odegrees to the horizontal. A distanced = 1.3 maway from the block is an unstretched spring withk = 3000 N/m. The block slides down the ramp and compresses the spring. Find the magnitude of the maximum compression of the spring.
