Answer:
The deceleration is 
Explanation:
From the question we are told that
The height above firefighter safety net is 
The length by which the net is stretched is 
From the law of energy conservation
Where 
is the kinetic energy of the person before jumping which equal to zero(because to kinetic energy at maximum height )
and 
is the potential energy of the before jumping which is mathematically represented at
and 
is the kinetic energy of the person just before landing on the safety net which is mathematically represented at
and 
is the potential energy of the person as he lands on the safety net which has a value of zero (because it is converted to kinetic energy )
So the above equation becomes
=> 
substituting values
Applying the equation o motion
Now the final velocity is zero because the person comes to rest
So
If f=140hz
speed=?
wavelength=?
without all information given, it would be difficult to answer but the formula is speed=frequency ×wavelength
Answer:
Net Force = 0
Explanation:
Causes objects to accelerate. Balanced Forces. Two equal forces push in opposite direction causing no change in motion causing net force = 0.
what happens at Point C is sublimation. the increase in temperature affects the Vapour pressure soon as you can see the curve is increasing with increasing pressure there is increase in temperature that is the sublimation Curve
