(a) What is the speed of the ball at the bottom of the first plane (in m/s)? (Round your answer to at least two decimal places.) m/s (b) How long does it take to roll down the first plane (in s)? (c) What is the magnitude of the acceleration along the second plane (in m/s2)? m/s²
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.
A volleyball starts from rest and accelerates with an acceleration of 0.405 m/s2 while moving down a 8.75 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 15.00 m, it comes to rest.
Given data:
The initial velocity of the volleyball is,
u = 0 m/s
Acceleration of the volleyball is,
a = 0.405 m/s2
A volleyball move down a distance of
d1 = 8.75 m inclined plane
After reaching the bottom volleyball, again rolls up another plane, where, after moving 15.00 m
d2 = 15 m
Formula used:
According to the kinematical equation of motion,
Where,
v- Final velocity
u- Initial velocity
a- Acceleration
d- Displacement
