Homework Statement
An 8.0Kg rocket is fired and encounters a force of air resistance of 4.9N. If the rocket's engines applied 100N of thrust:
A. What is the Net Force on the rocket?
B. What is the Rocket's Acceleration?
Homework Equations
(A) F=MA
(B) Is it (Vfinal - Vinitial)/T?
The Attempt at a Solution
(A)F=MA
F=(8.0KG)(A) = (8.0 x A) The paper tells me its 16.7N
(B) I don't know if this is the right equation... but it must be about 2.9 M/S2 to get A above.
