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: x=11
Step-by-step explanation:
First distribute 3 to both x and -3.
3x-9=24
Then add 9 to both sides to leave the x on its own.
3x=33
Divide by 3 on both sides.
X=11
The mass of a thin triangular plate bounded by the coordinate axes is 3 3/4.
<h3>How to calculate the mass?</h3>
It should be noted that mass simply means a quantity of matter that's in a body. It's the meaure of the inertia in the body.
In this case, from the complete question, the mass will be:
= 3/1000[1/24x⁴ - 25x² + 1000/3x]
= 15/4
= 3 3/4
