An electron of mass 9.1E-31 kg is released from rest at a distance of 7.1 E-10 m from a fixed electron. The force on the movable electron is given by the function F = 2.3E-28/r^2, where r is the distance between the electrons. Find the maximum velocity (in meters/second) of the moving electron after release.
The barrel has a length of 0.60 m and an opening whose radius is 2.8 10-3 m. A bullet (mass = 2.7 10-3 kg) has a speed of 380 m/s after passing through this barrel. Ignore friction and examine the average pressure of the expanding gas.
On an amusement park ride, passengers are seated in the horizontal circle of radius 6.5 m. The seats begin from rest and are uniformly accelerated for 24 seconds to a maximum rotational speed of 1.4 rad/s.
A ship sets out to sail to a point 212 km due north. An unexpected storm blows the ship to a point 156km due east of its starting point. How far must it now sail to reach its original destination.
