A 1.30-kg particle moves in the xy plane with a
velocity of = (4.10
î − 3.80 ĵ) m/s. Determine the
angular momentum of the particle about the origin when its position
vector is = (1.50
î + 2.20 ĵ) m.
If a particle with mass m moves with position ! r(t), then, the angular momentum is defined as ! L(t) = m! r(t) × ! v (t) and its torque is ! τ (t) = m! r(t) × ! a(t). Show that ! L′(t) = ! τ (t) . What are the consequences for both ! a(t) and ! L(t) when ! τ (t) = ! 0 for all t? THIS IS CALC 3 VECTOR STUFF MUST USE CALCULUS
a 3.00 kg block moving 2.09 m/s right hits a 2.22 kg block moving 3.92 m/s left. afterward, the 3.00 kg block moves 1.11 m/s left. find the momentum of the 2.22 kg block afterwards.
