A 0.2kg mass is attached to a spring that is compressed against a heavy brick. The mass begins at the origin of a coordinate system as shown (Note that +y is pointing down). At t=0s, the spring is released and the mass and brick are allowed to fall. The mass accelerates at 3.2m/s^2 due to the spring and 9.8m/s^2 due to gravity.

What is the displacement vector of the mass after 2.5s? Give both components below in m.

a. i:

b. j:

c. What is the direction of the total acceleration at t=0s and t=2.5s? Give your answer in degrees below the x-axis (i.e. the number should be positive.

t=0s

d. t=2.5s
