Answer:
240 ft
Explanation:
t = Time taken
u = Initial velocity = 96 ft/s
v = Final velocity
s = Displacement
a = Acceleration = 12 m/s² on Mars 32 ft/s² on Earth negative due to upward direction
Mars

Earth

Differentiating the first equation with respect to time we get

Equating with zero

Differentiating the second equation with respect to time we get
Equating with zero

Applying the time taken to the above equations, we get


Difference in height = 384-144 = 240 ft
The stone will travel 240 ft higher on Mars
Near the poles as the lines are the closest
Answer:
10 N
Explanation:
Work done is the dot product of the force magnitude with distance and cosine of the angle betweenthem.
Equation to use: W=|F|*|d|*cosθ
Your unknown is the force F; You have one equation, oneunknown.
40j=(F)*(4m)*cos(0)
F=40j/4m
F=10N
Answer:

Explanation:
We have to many data in different system, so we need transform everything to SI, that is

When we have all this values in SI apply a Energy Balance Equation,
![\dot{Q}_{cv}-\dot{W}_{cv}+\dot{m}[(h_1-h_2)+(\frac{V_1^2-V_2^2}{2})+g(z_1-z_2)]=0](https://tex.z-dn.net/?f=%5Cdot%7BQ%7D_%7Bcv%7D-%5Cdot%7BW%7D_%7Bcv%7D%2B%5Cdot%7Bm%7D%5B%28h_1-h_2%29%2B%28%5Cfrac%7BV_1%5E2-V_2%5E2%7D%7B2%7D%29%2Bg%28z_1-z_2%29%5D%3D0)
Solving for V_2

From the table of gas properties we calculate for
and 


For T_2;

Substituting in equation for V_2
