उत्तर

Given:

m = 2 kg,

T.E. = 40 J

To find:

Speed while crossing the mean position (vmax) = ?

Formula:

T.E. = `1/2 mv_"max"^2`

Calculation:

From formula,

`v_"max" = sqrt((2 xx T.E.)/m)`

= `sqrt((2 xx 40)/2)`

= `2 sqrt 10`

= 2 × 3.162

= 6.324 m/s

The speed of the particle while crossing the mean position is 6.324 m/s.
