Aprojectile is launched from ground level at angle u and speed v0 into a headwind that causes a constant horizontal acceleration of magnitude a opposite the direction of motion. a. find an expression in terms of a and g for the launch angle that gives maximum range. b. what is the angle for maximum range if a is 10% of g?

Explanation:

Given

Launch angle =u

Initial Speed is

Horizontal acceleration is

At maximum height velocity is zero therefore

Total time of flight

During this time horizontal range is

For maximum range

(b)If a =10% g

thus

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
