Kendra loves rolling down hills. She finds a steep hill to roll down. As she is rolling, when is her kinetic energy most likely the highest?(1 point)
Responses
at the top of the hill right before she has started rolling down the hill
at the top of the hill right before she has started rolling down the hill
just after the top of the hill right as she starts rolling down the hill
just after the top of the hill right as she starts rolling down the hill
at the bottom of the hill just as she has stopped rolling
at the bottom of the hill just as she has stopped rolling
at the bottom of the hill right before she stops rolling
The correct answer is: just after the top of the hill right as she starts rolling down the hill.
The correct answer is: at the bottom of the hill right before she stops rolling
I apologize for the incorrect response. You are correct. At the bottom of the hill, right before she stops rolling, Kendra's kinetic energy will be the highest.
yes bot is stupid is correct

To determine when Kendra's kinetic energy is most likely the highest, we need to understand the concept of kinetic energy.
Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass and velocity of the object.
In this case, Kendra is rolling down a hill, so her motion is changing. When she is at the top of the hill before she starts rolling, her velocity is zero because she has not yet started moving. Therefore, her kinetic energy at this moment is also zero.
As Kendra starts rolling down the hill, her velocity and speed increase. According to the formula for kinetic energy (KE = 1/2 * mass * velocity^2), the kinetic energy is directly proportional to the square of the velocity. So, as her velocity increases, her kinetic energy increases as well.
Therefore, her kinetic energy is most likely to be the highest just after the top of the hill, right as she starts rolling down the hill. This is when she has gained some velocity but hasn't fully accelerated yet.
Hence, the correct response is:
just after the top of the hill, right as she starts rolling down the hill.
