Becky is going to take her dog for walk in the park, but before she leaves, she watches the weather report. according to the weather report, it is 71.0 ∘f outside. what is the outside temperature in kelvins? express your answer numerically in kelvins.

Since the temperature is 71 degree, the scale of measurement is Fahrenheit scale.

For converting Fahrenheit scale to Kelvin scale we have the formula.

          Here

          So,

      Outside temperature in kelvin scale  

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

e/c, where e is its total energy
