Solve the following word problems. Show your solutions. Final answers should be highlighted and in sentence form. 1. A boy throws a ball horizontally from the top of a building. The initial speed of the ball is 20 m/s. Find the vertical and horizontal components of its velocity.
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.
![III. EVALUATION
Solve the following word problems. Show your solutions. Final answers should be highlighted
and in sentence form.
1. A boy throws a ball horizontally from the top of a building. The initial speed of the ball is 20
m/s. Find the vertical and horizontal components of its velocity.
2. A regulation volleyball court is 18.0 m long and a regulation volleyball net is 2.43 m high.
Alyssa Valdez has to make a serve so she strikes the ball a height h = 1.73 m directly above the
back line, and the ball's initial velocity makes an angle 50 degrees with respect to the ground.
Will she be able to make one good serve? Prove your answer quantitatively.
3. An object is whirled at the end of a string in a horizontal circle. If the period of one revolution
is 1.18 s, and the length of the sting is 0.93 m, find the centripetal acceleration of the object.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9324949f-f4a1-4f11-aa8c-d607884463cd%2F2854feee-c3cd-4355-a884-b7ba824167ce%2Foc2y5p6_processed.jpeg&w=3840&q=75)
