18. A 2-kg block is pushed against a spring with k = 500 N/m, compressing the spring by 20 cm. The block is then released, and the spring projects it along a frictionless horizontal surface and then up a frictionless incline of angle 45° as shown in the figure. What is the maximum height it travels up the incline before momentarily coming to rest? 20cm 20cm mmmmm 45°
