    Answer:

    1988 m

    Explanation:

    Range of a projectile

    R = U²sin2∅/g…………………. Equation 1

    Where R = Range, U = Initial velocity, g = acceleration due to gravity, ∅ = Angle of projection.

    Given: U = 150 m/s, ∅ = 60°

    Constant: g = 9.8 m/s².

    Substitute these values into equation 1

    R = 150²(sin60°)/9.8

    R = 22500(0.866)/9.8

    R = 1988 m

    Hence the Range of the projectile is 1988 m
