Auniform stick 1.5 m long with a total mass of 300 g is pivoted at its center. a 3.0-g bullet is shot through the stick midway between the pivot and one end the bullet approaches at 250 m/s and leaves at 140 m/s.
with what angular speed is the stick spinning after the collision?
ω= rad/s

2.2 rad/s

Explanation:

Given

Length of stick=1.5 m

mass m=300 gm

mass of bullet

approach velocity of bullet=250 m/s

Final Velocity of Velocity=140 m/s

Distance of Pivot to bullet hit is

Conserving Angular Momentum

Initial momentum

Moment of inertia of rod about Pivot

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
