Answer:
Depletion expenses for the first year is $210736.840
Explanation:
Depletion expenses= (Cost of coal mine - residual value) / Total tons of coal * tons extracted
=(1,001,000 - $0) / 57,000 tons * 12,000 tons
=$210736.8421
=$210736.840
Answer:
Initial Velocity= 49 m/s
Time period= 5 secs
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending
The initial velocity can be calculated using the expression below
u= √( 2gh)
Where g= Acceleration due to gravity= 98 m/s^2
h= height
Substitute the values we have
u = √(2*9.8*123)
u=√( 2410.8)
u = 49 m/s
the time period can be calculated as
(49/9.8)
= 5 sec
Hence time period is 5 secs
