Please solve quickly. Really quickly!thanks hero

Part II - Problem Solving 1. A vertical spring has an initial length of 16.0 cm. A mass of 450.0 g was attached to it and the final value is 18.5 cm. If this spring is set to motion with an initial stretch of 8.00 cm, determine: (Remember the FBD when dealing with forces) A. The spring constant B. The period of the oscillation (1:1, C:1) C. The maximum velocity (A:2) D. The maximum acceleration (1:1, A:1) (I:1, C:1) 2. An inclined plane of angle 0 = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure. A block of mass m=2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with speed v= 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest? (K:2. 1:2, A:2, C:2) m
