What is this problems angular momentum?
angular momentum L = Iω = (2mr²)(2π/T) = 2 * 61kg * (10.5m)² * 2π / 59s = 1432 kg·m²/s After moving, L = 1432 kg·m²/s = 2 * 61kg * (d/2)² * 2π / 47.79s (d/2)² = 89.3 m² d = 19 m Read More »

How to do this momentum problem?
take north in the +ve y direction so fullback momentum=82*5.5i opponent momentum =98*(-3.6i) as collision is perfectly inelastic,after collision they stick together so final velocity=(82*5.5i+98*(-3.6i))/(98+82) =0.545im/s Read More »

What is a momentum problem?
A car (1) with a mass of 1000kg traveling 20 m/s hits another car (2) with a mass of 500kg traveling 5 m/s. After the collision, car two has a velocity of 10 m/s. Assuming the collision is perfectly elastic, what is the velocity of car one ... Read More »

these can be solved with simple kinematics; since there are no horizontal forces, the horizontal motion of A remains the same at 24m/s therefore, the distance it travels will be 24t where t is the time of flight we find t by calculating how...

The angular momentum of system is: L = 2 Ig ω + Iw ω Ig = moment of inertia of each gerbil (m r²) Iw = moment of inertia of wheel (M R²) ω = angular velocity of gerbils and wheel (is the same) L = 2 m r² ω + M r² ω = (2 m + M) ω r² = (2 m +...

Let the original momentum be in the y direction. Since both balls have the same mass we can eliminate mass from the eqns to simplify the work So the original momentum/unit mass = 4.2m/s in the y direction After the collision we have v2*cos(...
