A particle has an initial velocity of 100 m/s up to the right at 30° with the horizontal. The components of the acceleration are constant at ax=-4m/s^2 and ay=-20m/s^2. Computing the horizontal distance covered until the particle reaches a point 60m below its original elevation would be
Vo=100m/sVox=100cos30°=86.6m/sVoy=100sin30°=50m/say=-20m/s^2Sy=voyt+1/2ayt^2-60=50t-1/2(20) t^2t=6sax=-4m/s^2Sx=voxt+1/2axt^2Sx=86.6(6) +1/2(-4) (6×6) Sx=448m
