Experimentally, the speed of a fired bullet was measured by a rifle as follows. Firing the bullet at a block of wood of mass M = 4.648 kg which is initially at rest on a smooth surface, attached to an elastic spring of constant k = 142.7 N / m. The mass bullet m = 7.870 g is embedded in the block of wood, causing the set to move 9.460 cm from the position of balance. Based on the previous information, (a) Determine the speed of the fired bullet; (b) Express the frequency of the set oscillation; (c) Calculate the position of the set as a function of time;
