Answer:

the maximum range for projectile motion (with no air resistance) is 45 degrees.

hope it will help you.

please mark me as brainlist.

Explanation:

R= u²sin2θ/g

H=u² sin²θ/2g

sin2θ/g= u²sin²θ/2g

2sinθcosθ= sin² θ/2

4cosθ=sinθ

tanθ=4

Answer:

A) The maximum range is 4 times the maximum height attained during its flight in the case of a projectile. B) In the case of a projectile the range R is related to the time of flight T as R=5T2. If g=10 ms−2 the angle of projection is 45o.
