Could I get some help? Thanks!

1. In the 2012 movie The Avengers, Ironman steers and pushes a nuc lear missile vertically upward toward a worm-hole that acts as a doorway for an invading army of aliens. Let the thrust provided by the missile be 12,640 N. Ironman's suit provides another 8,666 N of thrust. Ironman's mass is 170 kg and the missile's mass is 500 kg. Ignore air resistance, assume the mass of the missile's burnt fuel is negligible and use g = 9.80 m/s. Take up as the positive y-direction. a. Draw a free body diagram of Ironman and another FBD of the missile as they fly vertically up toward the portal. Use the F on A by B convention to label the forces b. Identify all Newton's Third Law pairs of forces i c. Use Newton's Second Law to write an equation for the system and calculate the d. Use Newton's Second Law to write an equation for Ironman and calculate the (M for missile and I for Ironman). part (a) magnitude of its acceleration. magnitude of the upward force Ironman exerts on the missile in his mighty grip. the two free body diagrams of

Explanation / Answer

let Frm be the force on missile man due to burning gases

Fri be the force on iron man

Fmi be the force on missile due to iron man

Fim be the force on iron man due missile

a)   

b. Frm and Fri are the reaction forces of gases where mass buring out conitnuosly in the downward direction

Fmi and Fim also constitues action reaction pair.

c. Frm + Fri - (mr + mi) g = (mr + mi) a

i.e

(12460 + 8666) -(500 + 170) * 9.8 = (500+ 170)* a

a = 21.73 m/s^2

d. Fri -(mig +Fim) = mi a

8666 - (170 * 9.8 + FIm) = 170 * 21.73

Fim = 3305 N
