A child blows a leaf straight up in the air from rest. The leaf accelerates at 1.0\,\dfrac{\text m}{\text s^2}1.0 s 2 m1, point, 0, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction upward.How much time does it take the leaf to displace 1.0\,\text m1.0m1, point, 0, space, m upwards?

Respuesta :

Answer:

Time taken by the leaf to displace by 1.0 m distance is

[tex]t = \sqrt2[/tex] seconds

Explanation:

As we know that initial velocity of the leaf is given as

[tex]v_i = 0[/tex]

now the acceleration upwards for the leaf is

[tex]a = 1 m/s^2[/tex]

The displacement of leaf in upward direction is

d = 1 m

so now we have

[tex]d = v_i t + \frac{1}{2}at^2[/tex]

[tex]1 = 0 + \frac{1}{2}(1) t^2[/tex]

[tex]t = \sqrt2[/tex] seconds
