can anyone give me the formula's to use?
5. ### How to get initial and final velocity? need help thanks

voko thank you... but i really dont understand hehehe sorry guys...
6. ### How to get initial and final velocity? need help thanks

why are we talking abouit energy now? im getting more confuse... oh my god... help!!!
7. ### How to get initial and final velocity? need help thanks

now its just got more complicated... hehehe can you just solve it then explain it to me why? really appreciate it voko... thanks
8. ### How to get initial and final velocity? need help thanks

is there an equation involve here?
9. ### How to get initial and final velocity? need help thanks

can anyone solve this?
10. ### How to get initial and final velocity? need help thanks

so your saying il make assumptions so theres no wrong answer here? outcome will depend on my assumptions?
11. ### How to get initial and final velocity? need help thanks

where are you masters???
12. ### How to get initial and final velocity? need help thanks

is this the right formula for getting the initial velocity? Vo = V - at Vo - initial velocity V - Velocity a - acceleration t - time
