i need an explanation on what to do that is ery somple to grasp

Problem 3 A block is attached to a spring on a frictionless surface as shown to the right. The block is pulled and held 4 cm to the right of its equilibrium position. m (a)[3 pts] It requires a force of 6 N to hold the block at this displacement. What is the spring constant, k? +X (b)[3 pts] The block is then released. It is observed that the frequency of the oscillations is 0.5 cycles per second. What is the mass of the block? (c)[3 pts] What is the angular frequency of the oscillations? (d)[3 pts] What is the maximum velocity of the block and where in the motion does this occur? (e)[3 pts] What is the maximum acceleration of the block and where in the motion does it occur? (f) [6 pts] Find an equation for the position, a(t), for the block as a function of time assuming the block is released at t = 0s
