AI kg mass is rests on a frictionless I meter long ramp and compresses a k = 4000 N/m spring a distance of 5 cm. The ramps angle of incline varies from 10 to 50 degrees, in increments of 10 degrees. For each angle of incline, determine if the block will slide off the top end of the ramp after it is released from the Spring. Output each angle of incline and whether of not the block reaches the top of the ramp.
