I THINK 5 is A and 6 is C
Answer:
A. 2.83 m/s
B. 39.55 degrees north of east
Explanation:
The velocity of the ball relative to the ground is the sum vectors of velocity of the ball relative to Mia and the velocity of Mia relative to the ground
If we take north east as positive direction then
Velocity vector of the ball relative to Mia is
Velocity of Mia relative to gorund is
<0, 5.3>
So velocity of the ball relative to the ground is
<1.8, -3.12> + <0, 5.3> = <1.8, 2.18>
Its magnitude is:
m/s
Its direction is
north of east
Hi! The inner most part of the atom (which is most of the atom) is occupied by electrons, therefore it’d take of most of its volume. Have a nice day!
Answer:
Explanation:
Let l be the length of the study area and w be the width of study area.
Area of rectangular part = l x w
A = l x w
384 = l x w
w = 384 / l .... (1)
length of the fence is equal to the perimeter.
P = 2 ( l + w)
from equation (1)
Differentiate with respect to l
for maxima and minima, it is equal to zero
l = 19.6 ft
so w = 19.6 ft
So, the required fencing = 2 ( 19.6 + 19.6) = 78.4 ft
