8.82 m. The 'range' means the distance along the positive x axis travelled by the projectile during its flight. First calculate the time elapsed over the flight using the SUVAT equation y = usin(θ)t - 0.5...

The answer is π/2. The key trick to solving this problem is to change variables by using the substitution x = sin(θ). We then need to change the differential and the limits too.

p = 17.9 kgm/s. p = mv. v = d/t. p = md/t. p = (5 x 50)/14
