Answer on Question #55749-Physics-Classical Mechanics

Astronauts mr. x and mr. y float in zero gravity space with no velocity. Mr. y throws a mass of 5 kg towards x with speed 2 ms. if mr. x catches it the change in velocity of x and y are

Solution

The change in momentum is

$$\Delta P = 5 k g \cdot 2 \frac {m}{s} = 1 0 \frac {k g m}{s}.$$

The change in velocity of $x$ is

$$v _ {x} = \frac {\Delta P}{(1 2 0 + 5) k g} = \frac {1 0 \frac {k g m}{s}}{(1 2 0 + 5) k g} = 0. 0 8 \frac {m}{s}$$

The change in velocity of $y$ is

$$v _ {y} = \frac {\Delta P}{(9 0 - 5) k g} = \frac {1 0 \frac {k g m}{s}}{(9 0 - 5) k g} = 0. 1 2 \frac {m}{s}$$
