A CD case slides along a floor in the positive direction of an x axis while an applied force a acts on it. The force is directed

along the x axis and has the x component Fax = 12x - 3x2, with x in meters and Fax in newtons. The case starts at rest at the position x = 0, and it moves until it is again at rest.
(A) Plot the work done on the case by a versus position x. (Do this on paper. Your instructor may ask you to turn in this work.)
(B) At what position is the work maximum?
(C) What is the maximum value of the work?
(D) At what position has the work decreased to zero?
(E) At what position is the case again at rest?

A tennis ball is served horizontally from 2.4m above the ground at net is 12m away and point 0.9 high will be ball clear the net
Schach [20]

Explanation:

Let us first calculate  long does it take to go 12m at 30m/s( assumed speed)

12/30 = 0.4 seconds

horizontal distance the ball drop in that time

H= (0)(0.4)+1/2(-9.8)(0.4)2

H= -0.78m

negative sign shows that the height of the ball at the net from the top.

Height of the ball at the net and from the ground= H1-H=2.4-0.78=1.62m

As 1.62m>0.9m so the ball will clear the net.

H_1= V0y t’ + ½ g t’^2

-2.4= (0)t’ + ½ (-9.8) t’^2

t’= 0.69s

X’=V0x t’

X’=(30)(0.96)

X’= 20.7m
