Erica (39 kg ) and Danny (46 kg ) are bouncing on a trampoline. Just as Erica reaches the high point of her bounce, Danny is moving upward past her at 4.6 m/s . At that instant he grabs hold of her.

Respuesta :

Answer:

V = 2.79 m/s

Explanation:

Momentum before = momentum after

Erica's momentum = 0

Danny momentum = 49 kg * 4.9 m/s = 240.1 kg-m/s

240.1 + 0 = (37 + 49) kg * V

86 V = 240.1

V = 2.79 m/s
