Answer: Last option
2.27 m/s2
Explanation:
As the runner is running at a constant speed then the only acceleration present in the movement is the centripetal acceleration.
If we call a_c to the centripetal acceleration then, by definition

in this case we know the speed of the runner

The radius "r" will be the distance from the runner to the center of the track



The answer is the last option
Answer:

Explanation:
Given:
- mass of solid cylinder,

- diameter of cylinder,

- mass of bucket of water,

<em>When the bucket is released to fall in the well, it fall under the acceleration due to gravity.</em>
We have formula for angular acceleration as:

where:
g = acceleration due to gravity
r = radius of the cylinder


Answer:
the vertical position is 1.1971m
Explanation:
Recall that

recall that 

this implies that distance = 12 * 5.0
= 60
therefore;
y = 1.1971m
