Beginning with newton's second law of motion, derive the equations of motion for a projectile fired from altitude h above the ground at an angle e to the horizontal and with initial speed equal to vo.

Considering the fire point at (0,h), x-direction positive to the right (→) and y-direction positive to up (↑) and the only force acting after fire is the projectile weight = -mg in the y-direction.

Step-by-step explanation:

First, we apply the Second Newton's Law in both x and y directions:

x-direction:

Integrating we have

Taking into account that a=(dv/dt) and v=(dx/dt):

y-direction:

Integrating we have

Taking into account that a=(dv/dt) and v=(dy/dt):

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
