The bob of a pendulum of length 1 = 0.8 m is released at an angle 0,= 60° with an initial speed of vo= 2 m/s. We are interested in the highest point the bob will reach. a) Draw a sketch including the trajectory of the bob and collect the available information, assigning names to all variables. b) Compared to the initial height, you expect the highest point the bob will reach to be [] higher [] The answer depends on the direction of the initial velocity of the bob. c) Which principle can you use to calculate the highest point the bob will reach? [] the same height [ ] lower
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.

assigning names to all variables.
b) Compared to the initial height, you expect the highest point the bob will reach to be
[] higher
[] The answer depends on the direction of the initial velocity of the bob.
c) Which principle can you use to calculate the highest point the bob will reach?

d) Calculate the highest point the bob will reach. Please use g= 10 m/s? and make sure your units
work out. Note: cos(60°) = 0.5
e) Compare your result with your answer to (b) and comment on the agreement.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F84f4843b-07b1-4077-ae0a-8943b9c9f3cb%2F5a02ac3d-1980-479d-a056-f9e237731cba%2F7knnq7o_processed.png&w=3840&q=75)
