<span>s = 60t - 3t^2
v = ds/dt = 60 - 6t
when it comes to rest, v = 0,
so t = 10 sec
now distance travelled = time taken x average velocity
= 10 x (60 + 0)/2
= 300 ft

The tree was approximately 40.8ft tall.
You use the equation, a^2+b^2=c^2.
12^2 + 39^2 = x^2, add the results of 12^2 and 39^2 to make 1665 = x^2. You can take the positive root of both sides, 3√185, and it equals 40.80441152, which is rounded to 40.8.
Your round it to 300 so the answer is 300
