The equation of motion of a rocket-propelled sled is, from Newtons law, m = f c
Question:
The equation of motion of a rocket-propelled sled is, from Newton’s law,
mυ = f – cυ
where m is the sled mass, f is the rocket thrust, and c is an air resistance coefficient. Suppose that m = 1000 kg and c = 500 N 0 s/m. Suppose also that υ(0) = 0 and f = 75,000 N for t ≥ 0. Determine the speed of the sled at t = 10 s.
