Ahockey stick of mass ms and length l is at rest on the ice (which is assumed to be frictionless). a puck with mass mp hits the stick a distance d from the middle of the stick. before the collision, the puck was moving with speed v0 in a direction perpendicular to the stick, as indicated in the figure. the collision is completely inelastic, and the puck remains attached to the stick after the collision.
what is the angular momentum lcm of the system before the collision, with respect to the center of mass of the final system?
express lcm in terms of the given variables.

The angular momentum of the hockey stick and puck system before collision is m_pv_0D .

The given parameters;

mass of the hockey, = mslength of the hockey, = Lmass of puck, = mpdistance the puck hits the stick from the middle of the stick's length, r = Dinitial velocity of the puck, = v₀

The linear momentum of the hockey stick and puck system before collision is calculated as;

$P_i = m_s v_0_s + m_p v_0\\\\P_i = m_s(0) + m_p v_0\\\\P_i = m_pv_0$

The angular momentum of the system before collision is calculated as follow;

$L = P_i \times r\\\\L = m_pv_0 \times D\\\\L = m_pv_0D$

Thus, the angular momentum of the hockey stick and puck system before collision is m_pv_0D .

Answer from: cheychey021203

The required angular momentum of the system before the collision is $m_{p}v_{0} D$ .

Given data:

The mass of hockey stick is, $m_{s}$ .

The length of hockey stick is, L.

The mass of puck is, $m_{p}$ .

The hitting distance from the middle of stick is, D.

The speed of puck is, $v_{0}$ .

Before collision, the total linear momentum is,

$P=m_{s}v_{0}+m_{p}v_{0}\\P=m_{s}(0)+m_{p}v_{0}\\P=m_{p}v_{0}$

And total Angular momentum before collision is,

$L=P \times D\\L=(m_{p}v_{0}) \times D\\L=m_{p}v_{0} D$

Thus, the required angular momentum of the system before the collision is $m_{p}v_{0} D$ .

Answer from: Quest

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
