When a body is moving in circular path at a
distance r from its center its velocity at any
instant will be directed tangentially. This is
what we call tangential velocity. It is
calculated as follows:
Vt=r(w)
where w = 5 rev/s (2m rad / rev) = 31.42
rad/s
Vt = 0.24(31.42) = 7.5 m/s
Answer:
60 sec.
Explanation:
The first person has to travel 200m at 2 m/s. It will take him 200/2=100 seconds to reach the gate. The second person is moving towards the gate at 2 + 3 meters per second so it will take her 200/5 = 40 seconds to reach the gate. Therefore, person #1 needs an extra 100-40 = 60 seconds.

<u>Answer:</u>
solubility
<u>Explanation:</u>
• Solubility is the property of an object that makes it dissolve in a solvent, thus making it 'disappear'. This is what is happening in the question.
• Conductivity is the property of a material that allows it to conduct electricity, i.e., it allows electricity to pass through it.
