The act of bowling a ball can be rather involved, but in its simplest form the bowler swings her arm in a roughly circular arc, releasing the ball just a moment after it passes through the bottom of the arc. By the time the ball is at the bottom of the arc, its speed is not changing anymore. A decent bowler can make the ball travel the length of the 60-ft alley in about 2.1 s. Ignore the (small) friction between the ball and the lane, so the ball travels at constant speed, once released. Calculate the speed of the ball moving across the alley when the bowler releases it? Round the final answer to the nearest whole number. In what direction is the ball accelerating when it’s at the bottom of the swing and the bowler has not yet released it? If the bowler has 2-ft-long arms, estimate the magnitude of the ball’s acceleration. Round the final answer to the nearest whole number. Estimate the total force on the 14-lb ball. Round the final answer to the nearest whole number. Estimate the tension in the bowler’s arm. Round the final answer to the nearest whole number.
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.
