A projectile is launched with a speed of 10m/s at an angle 30 degrees from the positive x axis. What is the range of the projectile?

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 - 0.5gt^2. Then use the value of t to find the range using x =ucos(θ)t.
