Answer:
1.6 m/s²
Explanation:
Weight equals mass times acceleration due to gravity.
F = mg
14.4 N = (9 kg) g
g = 1.6 m/s²
Most events in track and field are individual except relay races. Therefore, it would probably be true.
Answer: 
Explanation:
Given
Initial angular speed is 
Final angular speed is 
Time period 
Magnitude of the fan's acceleration is given by
Insert the values
Thus, fan angular acceleration is
The relationship between the initial velocity, final velociy, distance, and deceleration can be expressed in the following equation.
2(a)(0.270 m) = 0² - (5.70 m/s)²
The value of a (which is the deceleration) is 0.06 m/s². Thus, the answer is that the deceleration value is approximately 0.06 m/s².
