Question

A gun is set up on top of a plateau that is 600 m high. The gun fires a projectile with an initial velocity of 150 m/s [S10degreeD] at time t=0. The projectile lands at the bottom of the plateau. What is the velocity of the projectile 2 sec after being fired? (how to get 155 m/s [S17D] as answer)
