A man is transporting a trolley of mass 6 Kg and having Kinetic energy of 40 J. Compute its Velocity with which he is running?

Don't spam :)) ​

Sagot :

Explanation:

Given that,

Mass of a trolley, m = 6 kg

Kinetic energy of the trolley, K = 40 J

To find,

The velocity of with which he is running.

Solution,

The kinetic energy of an object is given by the formula as follow :

K = 1/2 mv²

v is velocity

Putting all the values we get :

v = √2k / m

v = √2×40/6

» v = 3.65 m/s

So, he is running with a velocity of 3.65 m/s.

msm555

3.65m/s

Answer:

Solution given:

mass(m)=6kg

kinetic energy: 40J

velocity(v)=?

we have

kinetic energy =½mv²

40=½*6*v²

[tex]\frac{40}{3}[/tex]=v²

v=[tex]\sqrt{\frac{40}{3}}=3.65m/s[/tex]
