That is it in simplest form, there is nothing else you can do to it.
Hope this helps :)
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:
the 3rd one or C
Step-by-step explanation:
585 miles per 9 hours
Step-by-step explanation:
715miles per 11 hours
/11 to determine miles per hour
65 miles per 1 hour
× 9 to determine miles per 9 hours
585 miles per 9 hours
In equation 1, When x = 0, y = -3 ( 0, -3)
And when y = 0, x = -3....( 3,0)
In equation 2, when x = 1, y = -4(1,-4)
and when y = 2, x = 5....(5,2)
You have to plot the points on graph paper and the solutions are where the two lines intersect.
You can use any points for x and y.
