Answer:
t = 8.3s
Explanation:
V = 100 m/s U = 0 m/s t = ? a = 12 m/s2
V = U + at
100 = 0 + 12 × t = 100 = 12t
12t = 100
t = 100/12 = 25/3
t = 8.3s
Answer:
total time =4.583 hour
Explanation:
We have given total distance = 60 mi
It is given that half of the distance traveled by a speed of 8 mph
We know that 
And second half of the distance traveled by a speed of 36 mph
So time 
So total time = 3.75 + 0.833 =4.583 hour
Quantity of electrical charge is measured in Coulombs.
The symbol is C.
b. C
Answer:
The force exerted by the ocean tide is directed to the right (east).
The force exerted by the wind is directed to the northwest (45° N of W).
We should separate the x- and y- components of the wind force, and evaluate each component separately.

We denote the direction to the right as the positive direction, so the x-component of the wind force is in the negative direction.
The resultant force is as follows:
 + [4242.64](\^{y})\\F_R = -2242.64\^{x} + 4242.64\^{y}](https://tex.z-dn.net/?f=F_R%20%3D%20%5B2000%20-%204242.64%5D%28%5C%5E%7Bx%7D%29%20%2B%20%5B4242.64%5D%28%5C%5E%7By%7D%29%5C%5CF_R%20%3D%20-2242.64%5C%5E%7Bx%7D%20%2B%204242.64%5C%5E%7By%7D)
The resultant acceleration can be found by Newton's Second Law:

The magnitude of the resultant acceleration is
