A halfback makes a turn on the football field. The halfback sweeps out a path that is a portion of a circle with a radius of 12-meters with a tangential velocity of 5 m/s. Determine acceleration of the halfback.

The right answer is "15.072 m/s".

Explanation:

The given values are:

Radius,

= 12 m

Time,

= 5 m/s

As we know,

⇒

On substituting the given values in the above formula, we get

⇒    

⇒    

⇒    

⇒    

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
