* In a first experiment, a 30-g clay ball is shot at a speed of 1.3 m/s horizontally from the edge of a table. The ball lands on the floor 0.60 m from the table. In a second experiment, the same ball is shot at the same speed, but this time the ball hits a wooden block that is placed on the edge of the table. The ball sticks to the block, and the block lands on the floor 0.06 m from the table. (a) Represent the second experiment with impulse-momentum bar charts, treating the x- and y-components separately; draw two sets of bar charts, first taking the wooden block as a system and then taking the block and the clay ball as a system (initial state: just before the clay ball hits the block; final state: just before the block touches the floor). Determine (b) the mass of the block and (c) the height of the table. Indicate any assumptions that you made.

Rocky the Flying Squirrel is carrying a nut of mass 0.5 kg while flying horizontally at a height of 15 m above the ground at a speed of 12 m/s. Bullwinkle is eagerly awaiting the
delivery of the nut on the ground. Rocky releases the nut as he is directly above Bullwinkle. How far from Bullwinkle will the nut land if Bullwinkle does not move?

IM-5 Jae throws a 0.350kg ball so that it is traveling at 7.50m/s
y
toward a wall, approaching the wall at an angle of 35.0°
as shown in the figure to the right. After hitting the wall,
the speed of the ball is still 7.50m/s but its direction has
changed and it is now traveling at an angle of 35.0° away
from the wall as shown to the right.
a) Sketch on your paper a figure like the one shown to
the right and show the vectors for the momentum
before impact, PB, the momentum after impact, PA, and
use them to find Ap, the change in momentum for the ball.
Clearly label each vector.
b) Calculate the sign and magnitude of Apx.
the change in momentum in the x direction.
c) Calculate the sign and magnitude of Apy
the change in momentum in the y direction.
d) If the collision lasts for 0.150 seconds, find the magnitude
of the average force on the ball during the collision. What
is the direction of the average force on the ball during the
collision? Answer this by showing an arrow and label it as…
Problem: During a match between Karasuno and Nekoma, Hinata hits the ball at an angle 40 degrees below the horizontal from a height of 2.75m. The ball hits the ground exactly after 0.70 seconds. Neglect air resistance.
*below the Horizontal equation: Vicos(theta)=Vix=Vfx
Viy=Vsin(theta) --> Y is NEGATIVE
Determine:
a) at what Velocity (in cm/s) did Hinata hit the ball?
b) how far from the net (in meters) did the ball land if he hit it 0.30m away from the net.
c) at what Velocity does the ball
hit the ground.
*pls answer with complete and systematic solution.
