An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only
Gnesinka [82]

Answer:

15.75 m/s

Explanation:

v = Velocity of the combined mass of astronaut and tools = 1.8 m/s

m_1 = Mass of astronaut = 124 kg

m_2 = Mass of tools = 16 kg

v_1 = Velocity of astronaut = 0

v_2 = Velocity of tools

As linear momentum is conserved

m_1v_1 + m_2v_2 =(m_1 + m_2)v\\\Rightarrow v_2=\frac{(m_1 + m_2)v-m_1v_1}{m_2}\\\Rightarrow v_2=\frac{(124+16)\times 1.8-124\times 0}{16}\\\Rightarrow v_2=15.75\ m/s

The velocity of the tools is 15.75 m/s

Looking at the position of the house and the tree, if the man ran starting from the house going
Aleks04 [339]

Average velocity of man is 2 m/s

<u>Given that;</u>

Distance between tree and house = 16 m

Time taken = 8 seconds

<u>Find:</u>

Average<em> velocity</em>

<u>Computation:</u>

Average velocity = Total distance cover / Time taken

Average velocity = Distance between tree and house / Time taken

Average velocity = 16 / 8

Average velocity = 2 m/s

During a race, a runner runs with an average velocity of 4.26 m/s toward city hall. What is the runner’s displacement after 167s
Artyom0805 [142]

Answer:

d = 711.42 m

Explanation:

Given that,

The average velocity of a runner, v = 4.26 m/s

Time, t = 167 s

We need to find the runner's displacement.

The average velocity of an object is equal to the displacement per unit time. It can be given by :

v=\dfrac{d}{t}\\\\d=vt\\\\d=4.26\ m/s\times 167\ s\\\\d=711.42\ m

So, the runner's displacement is 711.42 m.
