because it will pick it up while coming down not just flowing on low land<span />
        
             
        
        
        
Answer:u=4.04 m/s
Explanation:
Given
Mass m=85 kg
mass of Raft M=130 kg
velocity of raft and man  v=1.6 m/s
Let initial speed of Tyrone is u
Conserving Momentum as there is no external Force 
 
 


 
   
 
        
             
        
        
        
a = 3.09 m/s²
<h3>Explanation</h3>
This question doesn't tell anything about how long it took for the car to go through 105 meters. As a result, the <em>timeless </em>suvat equation is likely what you need for this question.
In the <em>timeless</em> suvat equation,

where
 is the acceleration of the car; is the acceleration of the car;
 is the <em>final</em> velocity of the car; is the <em>final</em> velocity of the car;
 is the <em>initial</em> velocity of the car; and is the <em>initial</em> velocity of the car; and
 is the displacement of the car. is the displacement of the car.
Note that <em>v</em> and <em>u</em> are velocities. Make sure that you include their signs in the calculation.
In this question,
Apply the <em>timeless</em> suvat equation:
 .
.
The value of  is greater than zero, which is reasonable. Velocity of the car is negative, meaning that the car is moving backward. The car now moves to the back at a slower speed. Effectively it accelerates to the front. Its acceleration shall thus be positive.

The resistance of a wire is directly proportional to the length of the wire. That is the longer the length of the wire, the higher the resistance and the shorter the length of the wire, the smaller the resistance.
        
             
        
        
        
Example of surface events are erosion and weathering. Erosion is the carrying of a particle from one place to the other and weathering is the breaking down of particles. These processes help in rock formation because this allows physical changes (grouping together or breaking down) on a certain substance. Subsurface events are those which happened underground such as the flow of underground water which subsequently allow the deposition of minerals, etc.
