A body is projected from height 60m with a velocity 10m/s at angle 30 degrees to horizontal the time of flight of the body is? (g=10m/s square)



Displacement of particle in y axis is=-60m Component of velocity in y direction is u sin theta=5 m/s S=uT-1/2aT2 -60=5T-5T2 T2 -4T +3T -12=0 T(T-4)+3(T-4)=0 (T+3)(T-4)=0 T=4s Time of flight is 4s
