shamim · Answer

Kinetic energy k.E=(1/2)*mv^2
Right?

shamim · Answer

I think c has larger velocity v. So c has greatest k.E

shamim · Answer

And we know potentialenergy P.E=mgh

anonymous · Answer

ok..

anonymous · Answer

so the one with the biggest height?? for PE?

shamim · Answer

I think a,b,c has same height. So they all has same potential energy

anonymous · Answer

Which projectile has the greatest kinetic energy upon impact?

anonymous · Answer

how do you know c has a larger velocity?

shamim · Answer

C

anonymous · Answer

how do you know?

shamim · Answer

C goes greatest horizontal distance. Because c has greatest horizontal velocity

anonymous · Answer

oh ok thanks duh I see! thanks a lot!

shamim · Answer

I guess all a,b,c have same mass m

anonymous · Answer

yeah i think thats assumed, and they are all at the same height because the ball is shot from the same height on all right?

shamim · Answer

U r most welcome!

shamim · Answer

Ya height h same for all a,b,c
