Step-by-step explanation:
E = m/2g(v²-u²)
2g×E = 2g×m/2g(v²-u²)
2Eg = m(v²-u²)
2Eg = mv² - mu²
mu²= mv² -2Eg
mu²/m = mv² -2Eg /m
u²= v² -2Eg
u = √v²-√2Eg

Answer:
about 11 years
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
solve for r
For the first event
P=3/(5+3)=3/8=0.375
Total became 2 red and 5 blue .... 7 total
For the second event
P=2/(5+2)=2/7= 0.2857
