Question

Once a ball leaves a table at 10 m/s, how long will it take to hit the floor

Answer 1

Answer:

The time taken for the ball to hit the floor as 1.02 seconds

Explanation:

As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation

$\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at}$

where Vf represents the final velocity

 Vi represents the initial velocity  

a represents the acceleration and

t represents the time

$\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at}$ after rearranging

 $\mathrm{t}=\frac{\mathrm{vf}-\mathrm{vi}}{a}$

  $\mathrm{t}=\frac{0-10}{9.8}$  = 1.022 seconds
