A man is carrying a trolley of mass 6kg and having K.E. of 40 J . Calculate its velocity with which he is running .

Sagot :

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....

The formula to find kinetic energy is -

[tex]K.E. = \frac{1}{2}*m* v^{2} [/tex]

Where,

[tex]m = mass[/tex]

and

[tex]v = velocity[/tex]

So, putting the values in the formula we get -

[tex]40 = \frac{1}{2} *6*v^{2} [/tex]

[tex] \frac{40}{3} = v^{2} [/tex]

[tex] \sqrt \frac{40}{3} = 3.6514 m/s[/tex]
