Aball on the end of a string is whirled around in a horizontal circle of radius 0.273 m. the plane of the circle is 1.31 m above the ground. the string breaks and the ball lands 2.87 m away from the point on the ground directly beneath the ball’s location when the string breaks. the acceleration of gravity is 9.8 m/s 2 . find the centripetal acceleration of the ball during its circular motion. answer in units of m/s 2

Explanation:

The centripetal acceleration is:

The acceleration on this axis is g and the y' is the distance above the ground so solve to t'

Now the distance and the time take the ball lands, can find the speed using

So finally the centripetal acceleration is

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
