Chapter 2, Problem 88PQ
In Example 2.12, two circus performers rehearse a trick in which a ball and a dart collide. We found the height and time of the collision graphically. Return to that example, and find height and time by simultaneously solving the equations for the ball and the dart.

people love to play with balls nowadays especially
during quarantine as theres not much to do. lets say we
have a ball that hits another ball that is at the rest. after
they hit and smash each other, the first ball moves
4m/s on the platform and makes an angle of 25
degrees while the other ball has a speed of 3m/s..
FIND
a)get the angle b3tween da d1rection of motion of da
second one (ball) and the original direction of motion of
da first one.
b) find da original sp33d of the first one
c)let me ask u this question. is the kinetic energy is
being conserving?
solve the following problem below. provide a complete solution with G (given), U (unknown), E (equation), and S (solution).
In the 1980s, one of Asia's fastest running women was a Filipino athlete names Lydia de Vega. In the 100 meter dash event in 1986 in Seoul, South Korea, she was clocked 11.53 s. Find her average speed
Two friends are playing billiards at an arcade center. One guy hit the cue ball
to strike at another ball where it is initially at rest. After the collision caused by the
ball that was at rest, the cue ball moves at 2.50 m/s along a line making an angle
e=14.0° with its original direction of motion and the second balI has a speed of 1.50
m/s. Find the answer for Part a,b and c. (Note: Both balls have the same mass.)
Part A: Find the angle 0 between the direction of the motion of the second ball and
the original direction of motion of the cue ball.
Part B: Find the cue ball's original speed?
Part C: Figure out whether kinetic energy is conserved?

- Consider a house with two rooms, which we call "left room" and "right room", respectively. We have a robot that is first located in the room on the left. This robot can move between two rooms. We now have 3 red spheres and 3 blue sphere in the room on the left. Our goal is to move all the items to the room on the right by the robot. Unfortunately, the robot can carry a maximum of two balls at a time. Another limiting rule is that the number of red spheres carried by the robot should not exceed the number of blue spheres. We define the state of each moment of the system as follows: (Robot presence/absence in the left room, number of blue balls in the left room, number of red balls in the left room) According to the above deseription, at the beginning of the system, the state is (1, 3, 3). At the end, the state should be (0, 0, 0). That is, there seems to be nothing in the room on the left and the robot is in the room on the right.
