The correct word to fill in the blank is:
<u>eccentric </u>
<u>
</u>Basing from the force-velocity curve, there are 2 muscle
actions, the concentric (shortening) and eccentric (lengthening). In eccentric
or lengthening muscle actions, force is high when the velocity is high. This is
opposite to concentric or shortening muscle actions, force is low when the
velocity is high. This means that in strength-gaining activities, the speed of
exercise should be slow during contraction, and it should be high when there is
expansion.
We will all chaotically burn to death!

Answer:
T = 0.83 seconds
Explanation:
Given that,
The mass attached to the spring, m = 1.5 kg
The amplitude of the spring, A = 0.3 m
The spring constant of the spring, k = 85 N/m
We need to find the period of the mass's motion. The time period in spring mass system is given by :
So, the period of the mass's motion is 0.83 seconds.
The ball will accelerate at a rate of
Explanation:
We can describe the motion of the ball by using Newton's second law, which states that the net force exerted on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
In this problem,
F = 14 N is the force exerted on the ball
m = 4.5 kg is the mass of the ball
Solving the equation, we find its acceleration:
So, the ball will accelerate at a rate of .
