I found mistake in the 2D Kinematics Notebook. In FA Qs 22 the answer says D (7.7m/s^2) but the answer should be 1.5m/s^2. 7.7m/2^2 is a result of forgetting to square T in the equation a=4(pi^2)r/T^2.

Rebbeca, Thank you. It is fixed now.

The unit plan references a projectile motion lab (marble launcher). Is this lab on this website somewhere?

Brad, I just posted two labs for this chapter. There are two extra files visible only for teachers. They include the solution to the labs. Thank you. Yuriy
