Missing question: (found on google)
<em>"What is the force of the pitcher's hand on the 0.145 kg ball during this acceleration phase?
</em>
<em>Express your answer with the appropriate units."</em>
Solution:
First of all, we need to calculate the acceleration of the ball, given by
where
v = 40 m/s is the final velocity
u = 0 is the initial velocity
is the duration of the acceleration phase
Substituting,
Now we can find the force exerted on the ball by using Newton's second law:
where
m = 0.145 kg is the mass of the ball
a is the acceleration
Substituting,
Answer:
the direction of the angular velocity of the wheels is north
