Answer: 600 m
Explanation:
Speed is defined as the distance traveled
in a especific time
:
Where:
is the speed of sound
the time you hear the thunder after you see the flash of lightning
We need to find the distance at which you are from the lightning strike:
Finding :
Finally:
In a collision an object experiences impulses, this impulse can be determined by the product of net force exerted upon it in the specific course of time.
<u>Explanation:</u>
An object experiences impulse due to the force exerted upon it in a particular time period.
i.e.
Where,
F - Force acted upon the object
- time interval for which the force act
According to the definition of Impulse, it is the integral of force (F) that acts upon any object over a time interval ∆t. It produces an equivalent change in the momentum and that too in the same direction as of the applied force (F).
Therefore, in order to find the impulse on an object, we have to find the force acted on it in a specific time interval.
Answer:
The angle is
Explanation:
From the question we are told that
The mass is
The radius is
The speed is
According to the law of energy conservation
The potential energy of the mass at the top is equal to the kinetic energy at the bottom i.e
=>
Here h is the vertical distance traveled by the mass which is also mathematically represented as
So
substituting values
