To find the area of the rectangle, you have to multiply the length by the width. 27 x 40 = 1,080 in ^2
N || P.
Since N is parallel to O, and O is parallel to P, then N must be parallel to P.
Answer:
0
Step-by-step explanation:
1/2 times 4 is 2 and 2 minus 2 is 0
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
