A 60.0 kg girl stands up on a stationary floating raft and decides to go into shore. She dives off the 180 kg floating raft with
padilas [110]
Momentum, p = m.v
m of the girl = 60.0 kg
m of the boat = 180 kg
v of the girl = 4.0 m/s

A) Momentum of the girl as she is diving:
p = m.v = 60.0 kg * 4.0 m/s = 24.0 N/s

B) momentum of the raft = - momentum of the girl = -24.0 N/s

C) speed of the raft

p = m.v ; v = p/m = 24.0N/s / 180 kg = -0.13 m/s [i.e. in the opposite direction of the girl's velocity]

julsineya [31]
We use the equation y = kx
y = 18, x = 2.5

18 = k2.5
k = 7.2

x = 6.4
y = 7.2*6.4
y = 46.08

Find the speed of an object that covers 400 km<br> in 5 hr.
Shalnov [3]
The speed of an object that travels 400 km in 5 hours, would be calculated simply by taking the distance of 400 and dividing it by the number of hours 5.

400 km/5 hours = 80km/hr.

The speed is 80 km/hr.
