Answer:
Step-by-step explanation:
Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown
near the earth's surface, and it moves along a curved path under the action of gravity only.
In projectile motion, the horizontal motion and the vertical motion are independent of each
other; that is, neither motion affects the other.
The horizontal component of the velocity of the object remains unchanged throughout the
motion. The vertical component of the velocity increases linearly, because the acceleration due to
gravity is constant (g=9.81 m/s2
).
= 0 cos
0 = 0 sin
To find the time of flight, determine the time the projectile takes to reach maximum height.
The time of flight is just double the maximum-height time.
Start with the equation:
= 0 + = 0 −
At maximum height,
= 0
The time to reach maximum height is

12 - x < 8
add x to both sides
12 - x + x < 8 + x
12 < 8 + x
re-write
8 + x > 12
Subtract 8 to both sides
8 + x - 8 > 12 - 8
x > 4
The graph B is matching the answer (x > 4)
So answer is B.

Answer:
i. a = 8.7, b = 7.1 and c = 11.2
ii. A = , B = and C =
Step-by-step explanation:
Given a right triangle with, b = 7.1 and B = .
I. Applying the trigonometric function to determine leg a, we have;
Tan θ =
Tan =
a =
= 8.675
The length of leg a is 8.7.
ii. To determine leg c,
Sin =
=
⇒c =
= 11.21
The length of leg c is 11.2.
iii. Given that: B = and C =
Then,
A + B + C = (sum of angles at a point)
A + + =
A + =
A = -
=
