I will be happy to critique your thinking and work. Break the inital velocity into two components: vertical, and horizontal.

sorry..wrong quest.

If you are Jackie, stop changing names. It does not help us assist you. I noticed you and Jackie have the identical IP address. Thanks.

THAT'S LAME..MY SISTER AND I ARE USING THE SAME COMPUTER... BOTH HAVE HOMEWORK TO DO U KNO

Ok, I will assume then you don't read each others work here, unless I send you the links. Thanks. The previous problem she posted is a good example to the one you just posted. If she did it, her explaination to you would be helpful.

OK

i DID

S = VCOS THETA * 2VSIN (THETA)/G

= 13 * 2(7.5) / 9.81

= 195 / 9.81

= 19.9M

IS THAT KOOL?
