A ball with mass m is attached to the end of a flagpole as shown in the figure below. The flagpole is connected to the side of a building at point P, has a length l, and makes an angle with the x-axis. (Consider the +x-direction to be to the right, the +y-direction upward, and the +z-direction to be out of the page.) At time t = 0, the ball becomes loose and begins to fall off of the flagpole...
10. + 0/3 points | Previous Answers SerPSET9 12.P.021. My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....

Two astronauts, each having a mass M, are connected by a rope of length d having negligible mass. They are isolated in space, orbiting their center of mass at speeds v. (Use any variable or symbol stated above as necessary.) (a) Treating the astronauts as particles, calculate the magnitude of the angular momentum of the two-astronaut system. 4- Mud (b) Calculate the rotational energy of the system. K-M2 By pulling on the rope, one of the astronauts shortens the distance...
A particle of mass m moves in a circle of radius
R at a constant speed v, as shown below. The
motion begins at point Q at time t = 0. Determine
the angular momentum of the particle about the axis perpendicular
to the page through point P as a function of time. (Use
any variable or symbol stated above along with the following as
necessary: t.)
The figure on the right illustrates a ball which is a uniform solid sphere having mass M and radius R. The ball is initially traveling in the positive direction with pure translational motion along a friction-less region of a horizontal surface (i.e. it slips with angular speed ω0-0). The initial translational speed of the ball is Vo. The friction-less region extends to a region having coefficient of kinetic friction Figure for WAH #10 V. Friction Friction-less No longer slipping '...

A ball of mass M, moving with speed V, strikes the end of a motionless, uniform stick of mass Mand length L, fixed at pivot point P. After the collision, the stick is rotating about the pivot point P as shown, and the ball rebounds with speed V/3. The moment of inertia of the stick about Pis (ML2/3.
