Answer: length = 62 yards and width = 3 yards
Step-by-step explanation:
Answer:
D. A(n) = P + (n-1)i*P
The formula to calculate the simple interest is:
Replace i by , then
SI = Pni
where n is the number of years.
So, for n-1 years, the simple interest is:
SI = P(n-1)*i
The Total amount is:
A(n) = P + (n-1)i*P
Given :
Initial velocity , u = 15 m/s .
Final velocity , v = 30 m/s .
Distance travelled , d = 40 m .
Also , this body is uniformly accelerating .
To Find :
(a) What is the acceleration .
(b) How long does this take .
Solution :
Let , acceleration be a .
By , equation of motion :
Also , by equation :
Hence , this is the required solution .
