Answer:
P.E = mgh = 120N
Step-by-step explanation:
v² = u² - 2as
At the top, the velocity is = 0
0² = 4² - 2 x 10 x s
4² = 20s
s = 16/20
s = 0.8metres.
It rose only 0.8metres.
Therefore P.E = 15 x 10 x 0.8
:. P.E = 15 * 8
:. P.E = 120N
Answer:
After 20 years the investment will be worth 11,000$
Step-by-step explanation:
in order to solve the problem you have to turn the percent into a decimal by moving the percent sign twice to the left. which will result in ".11"

multiply 550x20 and you get 11,000
