1. What is the linear momentum of a 27,500 kg spacecraft moving at 28,000 km per hour?
p ⃑=mV ⃑( p=mV )
28,000 km per hour = 7777.7778 m/s
p ⃑=(27,500kg)(7777.7778m/s)
p ⃑=213,888,889.5 kg·m/s
2. A 125 g rock is wedged in a tire that has a diameter of 0.70 meters. The moment of inertia is
0.0153 kg·m2
and the angular velocity vector is 80 Radians per second. How fast will the
rock be moving if it comes free?
H ⃑=I Ω ⃑(H=IΩ)
H ⃑=(0.0153 kg·m)(80r/s)
H´ =1.224 kg·m
