Whipple is beginning to feel as if he understands the concept of constant acceleration motion. After examining the kinematic equations of motion for constant acceleration, he decides to compare the speed of the ball upward at one point to when it is moving downward at the same height. He runs the experiment several times with different positive values of the initial velocity, and compares the speed of the tennis ball as it passes one value of y on its way up and on its way down. Whipple observes that the speed of the ball is the same on the way up as down. However, the sign of the velocity is positive when the ball is on its way up and negative when it is on its way down. O the answer depends on the value of the initial velocity. O the ball's speed is larger when the ball is traveling upward. O the ball's speed is larger when the ball is traveling downward.

Concept explainers

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

Question

Mehul.m.

Part 3 of 5 - To discover that when the
displacement is zero, the speed is the
same (velocity up vs. velocity down
when displacement in y is 0).
Whipple is beginning to feel as if he understands the concept of constant acceleration motion. After examining the kinematic equations of motion for constant acceleration, he decides to compare the
speed of the ball upward at one point to when it is moving downward at the same height. He runs the experiment several times with different positive values of the initial velocity, and compares the
speed of the tennis ball as it passes one value of y on its way up and on its way down.
Whipple observes that
the speed of the ball is the same on the way up as down. However, the sign of the velocity is positive when the ball is on its way up and negative when it is on its way down.
O the answer depends on the value of the initial velocity.
O the ball's speed is larger when the ball is traveling upward.
O the ball's speed is larger when the ball is traveling downward.
Whipple is incorrect. He should be careful to examine the speed of the tennis ball at the same value of y on its way up and on its way down.
