Ok I tried redoing the whole problem... KE= 36.125 J PE = 0 J I found the total E to be 36.125 J Then i found the PE2 to be 23.31 J (0.250) (9.81) (9.50) = 23.31 Then subtracted 23.31 from the total E 36.125 - 23.31 = 12.815 So the KE2 = 12.815 J Then I found the speed by calculating...

So, if v=0 then ke would = 0 as well because the energy is converted into gravitational energy?

Chemicist: I thought it would equal zero too that is where I am still confused...

Thanks! And for the last part of the problem at h=0 would the final speed be the same as the initial speed?

Homework Statement Drew kicks a ball (mass=0.250 kg) off his back porch at h= 1.50 m above the ground with an initial speed v= 17.0 m/s at some known angle. Find the initial kinetic energy of the ball. Find the initial potential energy of the ball. Find the kinetic energy and the speed v...
