In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A particle P P\,P is projected from a point on horizontal ground with speed 25 m s−1^{-1}−1 at an angle θ \theta\,θ above the horizontal. Air resistance is modelled as negligible. P P\,P lands on the ground 5 seconds later.
Find the value of θ\thetaθ.
Find the horizontal distance travelled by P P\,P before it lands.
