A block of clay is suspended as part of a ballistic pendulum (see Example 8.7). You have a gun that uses compressed air to fire a small 5.00 g ball into the clay. As you change the pressure of the air used to fire the ball, you can adjust the speed of the ball as it emerges from the gun. You fire the ball into the clay at a series of known speeds and measure the height to which the clay rises after the ball embeds within it. Your data are shown in the table below: Speed (m/s) Height (mm) 100 8.8 110 10.6 120 12.6 130 14.8 140 17.2 150 19.7 Make a plot of the square of the initial speed of the ball as a function of height. (Hint: Be sure to convert into SI units.) Using a linear “best-fit” to the data, determine the mass of the block of clay.

A 0.06kg bullet has a speed of 800m/s before it strikes a 1.06kg wooden block that is stationary on a horizontal frictionless surface and remains inside of it. What is the speed of the block after the bullet becomes embedded in it to one decimal place?
A 20 gg ball of clay traveling east at 2.0 m/sm/s collides with a 20 gg ball of clay traveling north at 2.0 m/sm/s.
What is the speed of the resulting 40 gg ball of clay?
Express your answer with the appropriate units.
An explosion in a rigid pipe shoots three balls out of its ends. A 6 g ball comes out the right end. A 4 g ball comes out the left end with twice the speed of the 6 g ball. From which end, left or right, does the third ball emerge?
