Question

The maximam horizontal range with is the value of angle of production (thita)

Answer 1

Answer:

max horizontal range is at 45°

Answer 2

Answer:

45 degrees

Explanation:

range=(u^2sin2a)/g

when the range is maximum, sin2a must be maximum

so when sin2a=1

=>2a=90                                                [since sin90=1]

=>a=45 degrees
