+ 2) meters.

We can find the velocity and acceleration functions by taking the first and second derivatives of x with respect to time:

velocity v(t) = dx/dt = -3(0.45)sin(0.45t + 2)

acceleration a(t) = d^2x/dt^2 = -3(0.45)^2cos(0.45t + 2)

To find the maximum velocity, we set v(t) equal to zero and solve for t:

0 = -3(0.45)sin(0.45t + 2)

sin(0.45t + 2) = 0

0.45t + 2 = nπ, where n is an integer

t = (nπ - 2)/0.45

To find the maximum acceleration, we set a(t) equal to zero and solve for t:

0 = -3(0.45)^2cos(0.45t + 2)

cos(0.45t + 2) = 0

0.45t + 2 = (n + 0.5)π, where n is an integer

t = [(n + 0.5)π - 2]/0.45

Note that there are infinitely many solutions for both t_max_v and t_max_a, as there are infinitely many values of n.

To find the values of maximum velocity and maximum acceleration, we can substitute the values of t_max_v and t_max_a into the corresponding velocity and acceleration functions:

v_max = -3(0.45)sin(0.45t_max_v + 2)

a_max = -3(0.45)^2cos(0.45t_max_a + 2)

However, since there are infinitely many solutions for t_max_v and t_max_a, we cannot find a unique value for v_max and a_max without additional information.
