Help me please

S3. You are designing a spring powered mortar, which is a tube encapsulating a spring inside it that can be compressed and then released to launch a projectile. You have to launch a projectile 90m. The spring can be compressed to a maximum of 0.5m due to design limitations. Assume that the projectile is launched from ground of mass m = 2kg to a maximum horizontal range of R level. R (a) What is the minimum speed with which the projectile must be launched? (b) What must be the minimum value of the spring constant k that will create the minimum speed you computed in part (a)?
