To solve this problem we will apply the concept of Impulse. Which is described as the product between the Force and the change in time. Mathematically this can be described as

Where,
F = Force
= Time
Our values are given as,
F = 1450N

Replacing we have,


Therefore the impulse delivered to the soccer ball is
or 
Explanation:
<h2>Speed is the rate of change of distance with time.</h2>
A. Tolerance. When you have an "Us vs Them" mentality it can never lead to acceptance.
Answer:
364.4 J
Explanation:
I = Moment of inertia of the forearm = 0.550 kgm²
v = linear velocity of the ball relative to elbow joint = 17.1 m/s
r = distance from the joint = 0.470 m
w = angular velocity
Using the equation
v = r w
17.1 = (0.470) w
w = 36.4 rad/s
Rotational kinetic energy of the forearm is given as
RKE = (0.5) I w²
RKE = (0.5) (0.550) (36.4)²
RKE = 364.4 J
