The formula to find kinetic energy is -
K . E . = 2 1 ∗ m ∗ v 2
Where,
m = ma ss
and
v = v e l oc i t y
So, putting the values in the formula we get -
40 = 2 1 ∗ 6 ∗ v 2
3 40 = v 2
3 40 = 3.6514 m / s
As we know that K.E = 1/2 mv² so by arranging it K.E ×2÷6 = v² now by putting values v²=13.33 m²/s² so v= 3.65 m/s....
To find the trolley's velocity from its kinetic energy, use the formula K . E . = 2 1 m v 2 . By substituting the values of mass and kinetic energy, we find that the velocity is approximately 3.65 m/s. This demonstrates the relationship between kinetic energy, mass, and velocity.
