PE = m x g x h KE = 0.5 x m x v2
a
981 J
b
1,962 J
c
40 J
d
80 J
There is not enough information provided to calculate the kinetic energy. We need to know the velocity of the cart at point A.
To calculate the kinetic energy of the cart at point A, we need to know its velocity. The given information does not provide the velocity. Therefore, we cannot calculate the kinetic energy without knowing the velocity.
To calculate the kinetic energy (KE) of the cart rolling through point A, we need to use the formula:
KE = 0.5 * m * v^2
Where:
- KE is the kinetic energy
- m is the mass of the cart
- v is the velocity of the cart at point A
In the given question, it states that the mass of the cart is 20 kg. However, it does not provide any information about the velocity at point A.
Therefore, to calculate the kinetic energy, we need to know the velocity of the cart at point A. Without this information, we cannot determine the correct answer.
Please provide the velocity at point A so we can calculate the correct kinetic energy.
