Problem $2-50$ polints $($appros $90$ min $)$ the has the following benematics

${}_{ar}=10ra\frac{d}{O},O_{ma}=0ra\frac{d}{s^2}$

$0ar=0ra\frac{d}{s},cos=+2ra\frac{d}{s^3}$

$\{\begin{array}{ccc}\text{:}& \text{l}\text{a}\text{s}1m\text{m}\text{i}\text{a}\text{n}\text{s}& ky\end{array}$

$\{\begin{array}{c}\text{:}b=\frac{1}{12}m\end{array}$

a$)$ Draw the kinematic and kinetie dagrams $(20$ points$),$

b$)$ Determino the Jolat Torguen at $0,A,$ and $8(40$ pointy$)$

Problems $-20$ points

Engine dats:

Air output velocity relative to the jal $=600\frac{m}{s}$ Jet data:

Two engines

Jet cruising speed $=200\frac{m}{s}$

Drag force is proportional to the squere of the jet speed D $=H_4^2$

If the jet is living horitontally parallef to the ground ata constant speed, determine:

a$)$ The mass flow of the engines, b$)$ If one engine stops Working, what will be the jet crulsing speed?

Problem $4-15$ points

Using the principle of impulse and momentum, calculate starting from rest the fime it tahes the pulling car to reach ves $\frac{m}{s}$
