Answer:
b
Step-by-step explanation:
20 + 30 + 25 + 15 + 25 = 115
115 / 5 = 23
20 - 23 = |-3|
30 - 23 = 7
25 - 23 = 2
15 - 23 = |-8|
25 - 23 = 2
3 + 7 + 2 + 8 + 2 = 22
22/5 = 4.4
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:
(3+2)²*4-10=x
Step-by-step explanation:
If it was a typo and is actually times 4, not divided by 4, then here is the answer:
(3+2)²*4-10=x
5²*4-10=x
25*4-10=x
100-10=x
90=x
If it actually was divided by 4, I don’t see any way it can be done.
