(a) The acceleration of the salt shaker is 1.18 m/s².

(b) The distance traveled by the baseball player before coming to rest is 204.1 m.

<h3>Acceleration of the salt shaker</h3>

The acceleration of the salt shaker at the given coefficient of kinetic friction is determined as follows;

a = μg

a = 0.12 x 9.8

a = 1.18 m/s²

Acceleration of the baseball player is calculated as follows;

a = μg

a = 0.4 x 9.8

a = 3.92 m/s²

<h3>Distance traveled by the baseball player</h3>

The distance traveled by the baseball player before coming to rest is calculated as follows;

v² = u² - 2as

0 = 40² - 2(3.92)s

0 = 1600 - 7.84s

7.84s = 1600

s = 204.1 m

The complete question is below:

A baseball player slides into third base with an initial speed of 40 m/s. If the coefficient of kinetic friction between the player and the ground is 0.40, how far does the player slide before coming to rest?

Gnesinka [82]

Answer:

1.97 * 10^8 m/s

Explanation:

Given that:

n = 1.52

Recall : speed of light (c) = 3 * 10^8 m/s

Speed (v) of light in glass:

v = speed of light / n

v = (3 * 10^8) / 1.52

v = 1.9736 * 10^8

Hence, speed of light in glass :

v = 1.97 * 10^8 m/s

I hate life do u know why
Katena32 [7]

Answer:

Most of us have experienced that pivotal peak of pain, anger or frustration in which we want to scream “I hate my life.” Yet, the feeling that a dark cloud has specifically settled over us and our experiences can feel pretty isolating. The truth is, no matter how singled out or overwhelmed we feel, and no matter what area we are struggling in, we are not alone.  More than half of U.S. workers are unhappy with their job.  One in 10 Americans struggles with depression. All of us have moments of utter despair. Escaping from this hopeless-seeming state may feel impossible. Yet, in reality, we are not doomed, and we are not powerless.  No matter what our circumstances, we can all learn tools to help us emerge from the darkest moments in our lives.
