Calculate the flight time of a ball moving in parabolic motion, with initial velocity 5.0m/s at angle 30 degrees from the horizontal travelling for 23 metres.
First, you would resolve the initial velocity into horizontal and vertical velocity. Then, using the correct suvat equation, s=ut, you can calculate for t. In this case, t=4.0s to 2 significan figures.
