to the horizontal. The kinetic
energy KE of the ball varies with horizontal displacement x as
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: When a ball is thrown upwards at an angle, its kinetic energy (KE) consists of two components: horizontal and vertical.
Step 2: The horizontal component of velocity remains constant, while the vertical component changes due to gravity.
Step 3: As the ball rises, its vertical velocity decreases, leading to a reduction in the overall kinetic energy. The graph representing KE vs. horizontal displacement (x) will depict the kinetic energy initially decreasing and then increasing as the ball falls back down.
Step 4: The appropriate representation for this behavior is a parabolic shape opening upwards, consistent with Option C.
Therefore, C.
