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)


approve if u like this ans

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)
