Answer:
15 m/s
Explanation:
Initial momentum = final momentum
(25 kg) (15 m/s) + (25 kg) (0 m/s) = (25 kg) (0 m/s) + (25 kg) v
v = 15 m/s
B) the distance from 2 credits of the wave
Distance= speed (multiplied by) time
To determine, the final velocity we use one kinematic equation. It would be 2ax = vf^2 - v0^2. The initial velocity would be zero since it starts from rest. Therefore, the equation would be:
vf = √(2ax) where a is the acceleration ( a = g ) and x is the height
vf = √(2)(9.8)(25)
vf = - 22.14 m/s
