Question

A marble rolls across a table for 6 meters in 2.3 seconds. What is the
velocity of the marble?

Answer 1

2.61
`(m)/(s)`

Step-by-step explanation:

v= d/t

v = 6m/2.3 s

v=2.61
`(m)/(s)`

Answer 2

`\boxed {\tt v\approx2.61 \ m/s}`

Step-by-step explanation:

Velocity can be found by dividing the displacement by the time.

`v=(d)/(t)`

The displacement is 6 meters and the time is 2.3 seconds.

`d= 6 \ m\\t= 2.3 \ s`

Substitute the values into the formula.

`v=(6 \ m)/(2.3 \ s)`

Divide.

`v=2.60869565 \ m/s`

Let's round to the nearest hundredth. The 8 in the thousandth place tells us to round the 0 to a 1.

`v\approx2.61 \ m/s`

The velocity of the marble is about 2.61 meters per second.
