Answer:
The velocity at the bottom is 
Explanation:
From the question we are told that
The total distance traveled is 
The mass of the block is 
The height of the block from the ground is h = 0.60 m
According the law of energy
Where PE is the potential energy which is mathematically represented as
substituting values
So
KE is the kinetic energy at the bottom which is mathematically represented as
So
substituting values
=> 
=> 
=>
Answer: The resultant displacement vector is 5.6km
Of the solar radiation entering the atmosphere, about 22.5% reaches the surface directly as direct radiation and is being absorbed. Thirty five percent of it is reflected back to the space. While 10.5% and 14.5% are scattered to the earth from the blue sky and from clouds, respectively. Also, 17.5 percent was being absorbed by the atmosphere. Thus leaving only 22.5% to be given directly to the Earth's surface. Also, another factor of this low value would be the transparency of the atmosphere. The atmosphere of the Earth has only an effective transparent to radiation from the sun of about .34 to .7 micrometer.
