The force-displacement graph for the strings of a
new type of graphite-head tennis racquet is shown
in diagram (a). The racquet is tested in a laboratory
by being secured vertically and then having a
special type of non-deforming tennis ball fired at
it horizontally, as shown in diagram (b). The initial
velocity of the ball as it strikes the racquet is
10 m s-1 east. After striking the racquet, the ball has
a velocity of 9.5 m s-1 west. The mass of the ball is
100 g.
What is the maximum displacement of the strings of
the racquet during this interaction?
velocity is displacement / time. Displacement is shortest distance between initial and final point
displacement = (final velocity square + initial velocity sq. )/ 2 * acceleration
Use s=ut+0.5at^2 (^2 notation for squared)Or calculate the final velocity from the known variables (Initial Velocity, Acceleration and Time)v=u+at Where V = Final Velocity, u = Initial Velocity, a = Acceleration, t = TimeThen calculate displacement (s) using s=0.5(u+v)t
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
Velocity: The changes happen in position is called velocity. Velocity is considered as the physical quantity. The magnitude and direction are necessary for this velocity.Velocity Formula :Unit: metre/second The formula for velocity is,`v=d/t`Here, the displacement is denoted as d and the time of the displacement is denoted as t.Velocity = change in position over a specific time intervalv= (xf - xo)/(tf - to)where xf is the final position and xo is the initial position.where tf is the final time and to is the initial time.
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)

Well, (final velocity) = (initial velocity) + (acceleration x time)
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
Final velocity = (Initial velocity) + (time)(acceleration)
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
Final velocity = Initial velocity +(acceleration * time)
height=acceletation(t^2) + velocity(t) + initial height take (T final - T initial) /2 and place it in for time and there you go

zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
