Tallula is driving her purple car and waving at everyone she sees. Her displacement in the x and y dimensions as a function of time are given below:

d_x = 10t + ln(t)

d_y = 0.5t ²

where d_x and d_y are in metres, and t is the time in seconds.

Determine her direction of motion at a time of t = 11 s. Her direction of motion should be expressed as a angle with respect to the x-axis. Give your answer to two decimal places
