This one is a toughy. A sandbag is dropped from a balloon at a height of 60 meters when the angle of elevation to the sun is 30 degrees. find the rate at which the shadow of the sandbag is traveling along the ground when the sandbag is at the height of 35 meters. [ the position of the sandbag is given by s(t) = 60 - 4.9t^2

Question

anonymous · Answer

i know how to solve it but i think i have an error in my derived equation. it is $$60-4.9t^2=x(\sec^230)+(\tan30)$$
