For example, leaves in a plant have chlorophyll, which can create glucose using light. All it needs is the material to do so. I can't really say that much. :D

What is the KE of a 250kg cart as it reaches the bottom if it’s velocity was 22m/s?

tensa zangetsu [6.8K]

Answer:

Kinetic energy = 60500 J

Explanation:

Given that,

Mass of the cart, m = 250 kg

Velocity of the cart, v = 22 m/s

We need to find the kinetic energy of the cart. This type of energy is possessed due to motion of an object. It can be given by :

$E_k=\dfrac{1}{2}mv^2\\\\E_k=\dfrac{1}{2}\times 250\times (22)^2\\\\E_k=60500\ J$

So, the kinetic energy of the cart is 60500 J.
