calculate the kinetic energy of a body of mass 2kg moving with a velocity of 0.1m/s.
mass=2kg
v=0.1m/s
k.E.=1/2mv^2
=1/2*2*(0.1)^2
=(0.1)^2
=0.01 J
looks good
Thanks a lot
To calculate the kinetic energy (KE) of a body, you can use the equation:
KE = 1/2 * mass * velocity^2
Given:
Mass (m) = 2 kg
Velocity (v) = 0.1 m/s
Now, we can substitute the values into the equation and calculate the kinetic energy:
KE = 1/2 * 2 kg * (0.1 m/s)^2
First, square the velocity:
KE = 1/2 * 2 kg * 0.01 m^2/s^2
Multiply the mass and the squared velocity:
KE = 1/2 * 2 kg * 0.01 m^2/s^2
KE = 0.02 kg m^2/s^2
So, the kinetic energy of the body is 0.02 kg m^2/s^2.
mass=2kg
v=0.1m/s
k.E.=1/2mv^2
=1/2*2*(0.1)^2
=(0.1)^2
=0.01 J
