A tomato of mass 0.17 kg is dropped from a tall bridge. If the tomato has a speed of 16 m/s just before it hits the ground, what is the kinetic energy of the tomato?
(1/2) m v^2
1/2x.17x(16)x(16)
To find the kinetic energy of an object, we can use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
In this case, the mass of the tomato is given as 0.17 kg and the speed just before it hits the ground is 16 m/s.
Plugging these values into the formula, we get:
Kinetic Energy = 1/2 * 0.17 kg * (16 m/s)^2
Simplifying the equation, we have:
Kinetic Energy = 1/2 * 0.17 kg * 256 m^2/s^2
Now, let's calculate the value:
Kinetic Energy = 0.5 * 0.17 kg * 256 m^2/s^2
Kinetic Energy = 21.76 Joules
Therefore, the kinetic energy of the tomato just before it hits the ground is 21.76 Joules.
