The kinetic energy of the cart is 300 J.
When you push a shopping cart, you apply force to move it, which transfers energy to the cart in the form of kinetic energy. This kinetic energy allows the cart to move. The energy transferred is proportional to the force you apply and the distance the cart moves.
The kinetic energy of the cart is the energy it possesses due to its motion. It is given by the equation KE = 0.5 * m * v^2, where m is the mass of the cart and v is its velocity.
The energy transferred by a rollercoaster cart is in the form of kinetic energy. As the cart moves along the track, potential energy is converted to kinetic energy, increasing the speed of the cart. The amount of energy transferred depends on factors such as the height of the initial drop and the mass of the cart.
If it were released from the top of the ramp, the cart would have maximum kinetic energy at the bottom of the ramp since the gravitational energy at the top of the ramp is converted into the kinetic energy of the cart.
Potential energy is highest at the top of a roller coaster when the cart has the highest elevation. As the cart descends, potential energy is converted into kinetic energy, reaching its maximum at the bottom. The relationship between potential and kinetic energy is a transfer of energy, as one decreases while the other increases.

At the start, potential energy is converted to kinetic energy as the cart descends. Kinetic energy is then converted back to potential energy as the cart ascends a hill. Friction between the cart and the track may also cause some energy to be converted to heat.
If the mass of the cart is increased, the kinetic energy of the cart will also increase as it rolls down the ramp. The velocity of the cart will increase as well, since the kinetic energy is directly proportional to both mass and velocity squared.
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. Therefore, if you do 100 J of work on a cart with no friction, its kinetic energy will increase by the same amount, resulting in a total kinetic energy increase of 100 J.
The same force could not be applied to travel the same distance if there is a larger mass in one instance. Applied force will accelerate a given mass twice as much as a mass half as large. If both are moving the same distance, the 20-brick cart had more kinetic energy when in motion.
When they're parked they do (which is zero). If a truck and golf cart were both moving at the same non-zero speed, the truck, being more massive, would have the greater kinetic energy.
Kinetic Energy = (1/2) x (M) x (V2) = (1/2) x (14) x (49) = 7 x 49 =343 joules
Yes.
