The most common liquid on planet earth is water
Their final velocity is 3.6 m/s
Explanation:
We can solve this problem by using the law of conservation of momentum. In fact, in absence of external forces, the total momentum of the system (Jose+Jeff) must be conserved before and after the collision. Therefore we can write:
where:
is the mass of Jose
is the initial velocity of Jose
is the mass of Jeff
is the initial velocity of Jeff, which is standing
is the final combined velocity
Re-arranging the equation and solving for v, we find their final velocity:

Answer and Explanation:
Tropical storm:
The point at which the tropical depression intensifies and can sustain a maximum wind speed in the range of 39-73 mph, it is termed as a tropical storm.
Hurricane:
A hurricane is that type of tropical cyclone which includes with it high speed winds and thunderstorms and the intensity of the sustained wind speed is 74 mph or more than this.
Hurricanes are the most intense tropical cyclones.
The only difference between the tropical storm and hurricane is in the intensity.
