A 2 kg mass is attached to a spring with spring constant 50 N/m. The mass is driven by an external force equal to f(t) = 2 sin(5t). The mass is initially released from rest from a point 1 m below the equilibrium position. (Use the convention that displacements measured below the equilibrium position are positive.)

My question and answer is in the image. Can you please check my work?
A 2 kg mass is attached to a spring with spring constant 50 N/m. The mass is driven by an external force equal to
f(t) = 2 sin(5t). The mass is initially released from rest from a point 1 m below the equilibrium position. (Use the
convention that displacements measured below the equilibrium position are positive.)
(a) Write the initial-value problem which describes the position of the mass.
2y"+50y=2cos(5t)
(b) Find the solution to your initial-value problem from part (a).
(1+(1/2)tcos(t))cos(5t)-(1/2)tcos(t)
(c) Circle the letter of the graph below that could correspond to the solution.
B
(d) What is the name for the phenomena this system displays?
Resonance
