Answer:
xf = 5.68 × 10³ m  
yf = 8.57 × 10³ m  
Explanation:
given data 
vi = 290 m/s
θ = 57.0°
t = 36.0 s
solution
firsa we get here origin (0,0) to where the shell is launched
xi = 0                            yi = 0
xf = ?                            yf = ?
vxi =  vicosθ               vyi = visinθ  
ax = 0                          ay = −9.8 m/s
now we solve x motion: that is 
xf = xi + vxi × t + 0.5 × ax × t²     ............1
simplfy it we get 
xf = 0 + vicosθ × t + 0
put here value and we get 
xf = 0 + (290 m/s) cos(57) (36.0 s)
xf = 5.68 × 10³ m  
and 
now we solve for y motion: that is 
yf = yi + vyi × t + 0.5 × ay × t
²     ............2
put here value and we get 
yf = 0 + (290 m/s) × sin(57) × (36.0 s) + 0.5 × (−9.8 m/s2) × (36.0 s)  ²
yf = 8.57 × 10³ m

Answer:
Both forces act along the line joining the objects like masses or charges. And both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law.

There are many forces that make an object move. 
· An Unbalanced force acting on an object
· Energy applied to an object.
