Which statement about the kinetic energy of the ball is true? a
Kinetic energy is scalar (direction does not matter), and it depends on the ball’s mass and height.
b
Kinetic energy is a vector (direction matters), and it depends on the ball’s mass and speed as it goes down the hill.
c
Kinetic energy is a vector (direction matters), and it depends on the ball’s mass and height.
d
Kinetic energy is a scalar (direction does not matter), and it depends on the ball’s mass and speed as it goes down the hill.
