physics- dynamics, Newton's laws

A Saturn V rocket has a mass of 2.75 x 10^6 kg and exerts a force of 33 x 10^6 N on the gases it expels. Determine (a) the initial vertical acceleration of the rocket, (b) its velocity after 8 seconds, and (c) how long it takes to reach an altitude of 9500m. (Ignore the mass of gas expelled and assume g remains constant.

college Physics- friction on an inclined plane

A block is given an initial speed of 4.0 m/s up a 22° plane. (a) How far up the plane will it go? (b) How much time elapses before it returns to its starting point? Ignore friction.
