A ball thrown up. A ball is thrown straight up. Ignoring air resistance, what is the velocity and acceleration of the ball at its highest point? O A. v= 0; a = 9.8 m/s² down O B. v= 0; a=0 OC. O D. v= 9.8 m/s down; a = 0 v = 9.8 m/s up; a = 9.8m/s² up
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.

False. Which of the following statements is false?
O A. Kinematics describes how objects move.
O B. Velocity describes the rate of change of position with time.
O C. Displacement is a scalar quantity that describes the change in position of an object.
O D. Acceleration describes the rate of change of velocity with time.
True. The initial and final positions of an object in one-dimensional motion are the same. Which of the following statements is true?
O A. The distance and displacement are both zero.
O B.
The distance travelled is zero while the displacement is non-zero.
O C.
Both the distance and displacement cannot be computed.
O D. The distance travelled is non-zero while the displacement is zero.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5c51225c-006d-4a86-a4a7-112461a587b3%2F756ea810-f7e6-429f-b9bc-e816ddde8f3b%2Fs9sl3og_processed.jpeg&w=3840&q=75)
