Answer:
(a) Angular velocity will be 125.6 rad/sec
(b) Linear velocity will be 144.44 m /sec
(c) Centripetal acceleration = 1849.3031 g
Explanation:
We have given diameter d = 2.30 m
So radius r = 
(a) Speed is given as 1200 rev/min
We know that angular velocity is given by 
(b) Linear speed is given by 
(c) Centripetal acceleration is given by
We know that 
So 
Answer: If you make certain decisions like changing your diet (for good or worse) increasing physical activity, or playing more video games, things like these can affect your wellness and health for the worse or better.
Answer:
48
Explanation:
you basically divide 1200 into 25
Answer:
3 m/s
Explanation:
Average Speed = 
Plug in the numbers, it will be (6m + 3m) divided by (2s + 1s), which is 9m/3s, which equals to 3m/s.
Answer:
False
Explanation:
The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².
Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,
s = 1/2gt² ⇒ t = √(2s/g)
Since. s = height is the same for both objects, they land at the same time neglecting air resistance.
