3a A 0.2 kg 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 3.2 m/s due to the spring and 9.8 m/s due to gravity. > +X What is the displacement vector of the mass after 2.5 s? Give both components below in m. 2 5. 3c What is the direction of the total acceleration at t = 0s and t = 2.5 s? Give your answer in degrees below the x-axis (i.e. the number should be positive. t = 0s No answer Incorrect The answer you gave is not a number. 6. 3dt = 2.5 s 3a A 0.2 kg mass is attached to a spring that is compressed against a heavy brick.
