Question 46

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A particle is projected from a point on horizontal ground with speed 20 m s−1^{-1}−1 at an angle of 35° 35°\,35° above the horizontal. Air resistance is modelled as negligible.

Find the two times at which the particle is 4 m above the ground.
