Answer» ANSWER: R15=2u2/g(cos15×sin15) so R 45degree=R15×2u

a projectile is thrown with an initial velocity u and angle 15 to the horizontal has a range R if the same projectile is thrown at an angle of 45 to the horizontal with speed 2u its range will be

Answer»

ANSWER:

R15=2u2/g(cos15×sin15)

so R 45degree=R15×2u
