<u>Answer</u>
The correct answer is A.
<u>Explanation</u>
The given triangle is a right triangle.
The length of the hypotenuse is
units.
The given angle is
.
The unknown side
is adjacent to the given angle.
We can therefore use the cosine function to find
.
Recall the mnemonics CAH.
This means that;

This implies that,

We multiply both sides by
to get,


We evaluate to get

Therefore the length
of the side of the triangle is
units to the nearest tenth.

Answer: 5.075Ns
Explanation:
Given the following :
Mass of ball = 145g
Initial Speed of ball = 15m/s
Final speed of ball when hit by the batter = - 20m/s ( Opposite direction)
The impulse of a body is represented using the relation:
Force(f) * time(t) = mass (m) * (final Velocity(V) - initial velocity(u))
Therefore, using:
m(v - u) = impulse
Mass of ball = 145 / 1000 = 0.145kg
Impulse = 0.145(- 20 - 15)
Impulse = 0.145(-35)
Impulse = 5.075Ns
