Answer to Question #221782 in Physics for Sadia Shafique

Question

 Will Ferrell's water rocket of mass 5.85 x 10² g accelerates vertically upward at 26.0 m/s² during launch, overcoming both gravity and air resistance.

(a) Draw a free-body diagram of the rocket during launch once it has departed from the launch pad.

(b) Calculate the thrust force applied by the rocket engine during launch if the air resistance acting on the rocket is 0.95 N.

Answer 1

a)

b)

$$F_{thrust}=0.585(9.8)+0.95=6.68\ N$$
