Carmen and judi dock a canoe. 77.0-kg carmen moves forward at 4.7 m/s as she leaves the canoe to step onto the dock. at what speed and in what direction do the canoe and judi move if their combined mass is 115 kg.

3.15m/s

Explanation:

Conservation of momentum

M1V1=M2V2

77kg*4.7m/s=115kg*V2

So therefore, V2=77kg*4.7m/s/115kg

=3.15m/s

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

this could be newton#'s law of cooling. the cooling curve is exponential
