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

Respuesta :

Answer:

2.61 [tex]\frac{m}{s}[/tex]

Explanation:

v= d/t

v = 6m/2.3 s

v=2.61 [tex]\frac{m}{s}[/tex]

Answer:

[tex]\boxed {\tt v\approx2.61 \ m/s}[/tex]

Explanation:

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

[tex]v=\frac{d}{t}[/tex]

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

[tex]d= 6 \ m\\t= 2.3 \ s[/tex]

Substitute the values into the formula.

[tex]v=\frac{6 \ m}{2.3 \ s}[/tex]

Divide.

[tex]v=2.60869565 \ m/s[/tex]

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

[tex]v\approx2.61 \ m/s[/tex]

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