Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
Answer:
9 ft*lb
Explanation:
super simple but you just have to understand that the integral is going with the curve
work = integral a to b of f(x)dx = integral 0 to 9 of 10/(1+x)^2dx = 9ft*lb
(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?

The speed limit in the school zone in Florida may not be less than 15 miles per hour excluding the local directive. No school zone speed limit intends to be more than 20 miles per hour in an urbanized zone as well-defined in section 334.03. The speed limit may possibly in force only all through those times 30 minutes before or during and 30 minutes after the periods of time when pupils are incoming at a regularly organized school session. Stable signs labeling school zones and school zone speed limits shall be identical in size, color and shall have the times all through which the restraining speed limit is compulsory clearly designated thereon.
