Question

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

Answer 1

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

Step-by-step 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}=(0-10)/(9.8)` = 1.022 seconds
