Kathrine lets go of a cube of mass of m = 5 kilograms on her physics demo device she created. Her cube goes down a super smooth slide surface that has a height vertical distance of h=85 cm. At the end of the slide, her cube crashes into and sticks to the lower end of a vertical pole that has a mass M=10.5 kg and length 1-2.00m. Right after the crash, the pole pivots about a hinge point near its upper end through an angle (theta) before it stops for a moment. See the image given below to visualize Katherines system. You are tasked with Figuring out the following three things The speed of her cube just before it hits the pole The angular speed of the pole just after the crash The angle (theta) through which the pole pivots a. b.

A solid ball of mass 0.10 kg and radius 2.8 cm is released from rest on a no-slip surface at a height of 0.75 m above the bottom of the track, as shown. After reaching its lowest point, the ball begins to rise again, this time on a frictionless surface. Find: a) the ball's angular speed when it is on the frictionless side of the track and b) the height ball rises on the w = 120 rad/s; h = 0.54 m frictionless side.
