Answer:
4 J
Explanation:
As I guess,
From the equation,
work done = force × distance travelled
= 2 × 2
= 4 J
There are no conversions since all are given in the standard form.
Using the following formulas for projectile motion:
Height, H = ( Vo^2 * sin theta^2 )/g
Range, R = ( Vo^2 * sin 2*theta )/g
Rearranging in terms of Vo^2:
Vo^2 = gH / sin theta^2
Vo^2 = gR / sin 2*theta
Equating the two formulas to each other to solve for the angle theta:
gR / sin 2*theta = <span>gH / sin theta^2
</span>
Substituting the given values:
(9.8)(111) / sin 2*theta = (9.8)(72.3)<span> / sin theta^2
</span>angle = 52.36 degrees
Therefore, the angle of launch is approximately 52.36 degrees.
