initial velocity = Vi = ucos@ (i) + usin@j


after t time ,

 (vertical comp of velocity ) Vy = (usin@-gt) (j)



horizontal component remains same ..

                   Vx = ucos@


final velocity (Vf) = (ucos@) (i) + (usin@-gt) (j)


change in velocity = Vi- Vf = dV = gt (j)


dV = gt  (change in velocity after time t)

Dear student,

Horizontal component of velocity remains same...         

So, Vx = ucos@


final velocity (Vf) = (ucos@) (i) + (usin@-gt) (j)


change in velocity = Vi- Vf = dV = gt (j)


dV = gt  (change in velocity after time t)
