A ball having mass m is fastened at the end of a flagpole that is connected to the side of a tall building at point P, shown in the figure. The length of the flagpole is, and it makes an angle e with the x axis. The ball becomes loose and starts to fall with acceleration -99. (Use any variable or symbol stated above along with the following as necessary: t.) (a) Determine the angular momentum of the ball about...

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....

At time t = 0, a 4.0 kg particle with velocity v = (5.0 m/s) i - (6.0 m/s) j is at x = 6.0 m, y = 5.0 m. It is pulled by a 2.0 N force in the negative x direction. What is the angular momentum of the particle about the origin? (Express your answer in vector form.) What torque about the origin acts on the particle? (Express your answer in vector form.) At what rate is the...

This is an interesting phenomenon, and a very difficult one to explain. Both torque and angular momentum must be treated as vectors. Torque causes angular momentum to change according to the following equation: delta L rightarrow = rightarrow delta T To use this equation the direction of a torque vector must be defined. Follow the moment arm with the fingers of your right hand. Then turn your fingers to follow the force. As you do this, your thumb will point...

The figure shows a ball with mass m = 0.237 kg attached to the end of a thin rod with length L = 0.607 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically upward position, with zero speed...

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.

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.)
