Answer:

Explanation:
It is given that,
Distance between the spotlight and the wall, y = 24 m
Height of the woman, h = 2 m
The woman walks toward the building at the rate of 0.6 m/s, 
In the attached figure, triangle ABC and MNC are similar. So,
............(1)

When she is 2 meters from the building. So x = 24-2 = 22 m

Differentiating equation (1) i.e.




So, her shadow is decreasing at the rate of 0.059 m/s. Hence, this is the required solution.
Gravitational potential energy=mass*gravitational acceleration*height
Kinetic energy = 0.5*mass*velocity²
So with the given data
K.E 0.5*1*x²=12.5 v²=12.5÷(0.5*1)
v=√12.5÷(0.5*1) v=5
GPE mass*gravitational acceleration*height
1*9.81*h=98
h=98÷(9.81*1)
h= 9.98 m
Normal force, weight, Kinetic friction, and air resistance are a few I think of the top of my head.
I hope this helps
Answer:
5833.33
Explanation:
= Angular acceleration
= Number of revolutions
= Initial angular speed = 0
t = Time taken = 2 s
Final angular speed

From the equation of rotational motion we have


The number of revolutions is 5833.33
The answer is radiation I believe
