Question

what is the maximum distance we can shoot a dart,from ground level provided our toy dart gun gives a maximum initial velocity of 2.7m/s and air resistance is negligible​

Answer 1

R = v^2 sin 2 theta / g

The range provides the distance a projectile can travel

R(max) = v^2 / g if theta = 45 deg

R = 2.7^2 / 9.8 = .74 m
