i can, but it would be different depending on the angle that he jumped 2.5 m/s. But, no matter what, the jumper's total energy will increase because of the jump. How can I apply it to this problem without a specific direction? I need to solve the answer soon.

Homework Statement A 105 kg acrobat jumps up off a platform at a velocity of 2.50 m/s and lands on a teeter-totter 3.00 m below, where another acrobat is waiting. If the waiting acrobat has a mass of 62.5 kg, how high does she get? Homework Equations KE=(1/2)mv^2 PEg= mgh The...

thank you! i figured that the velocity must have been an unknown constant (which would be ridiculous) or 0. I just wanted verification. Thank you for the fast reply guys!

Homework Statement After a malfunction, an astronaut escapes from a doomed spacecraft by using an escape pod that is blown off of the ship. The small explosion sends the pod flying away at 34.9 m/s, while the main ship moves in the opposite direction at the speed of 1.89 cm/s. If the...
