a mass if 10kg move with a velocity of 4ms-1find it kinetic energy.
(1/2) m v^2
= .5 *10 * 16
= 80 Joules
a mass of 10kg move with a velocity of 4ms-1 find it kinetic energy
Find its kinetic energy
To find the kinetic energy of an object, you can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
Given that the mass of the object is 10kg and its velocity is 4m/s, you can plug in these values into the formula to find the kinetic energy:
Kinetic Energy = (1/2) * 10kg * (4m/s)^2
First, square the velocity:
Velocity^2 = (4m/s)^2 = 16m^2/s^2
Next, multiply the squared velocity by the mass:
Kinetic Energy = (1/2) * 10kg * 16m^2/s^2
Kinetic Energy = 80kg m^2/s^2
Therefore, the kinetic energy of the object is 80 kilogram meter squared per second squared (kg m^2/s^2).
