Earthquakes are essentially sound waves—called seismic waves—traveling through the earth. Because the earth is solid, it can support both longitudinal and transverse seismic waves. The speed of longitudinal waves, called PP waves, is 8000 m/sm/s. Transverse waves, called SS waves, travel at a slower 4500 m/sm/s. A seismograph records the two waves from a distant earthquake. The SS wave arrives 2.0 minmin after the PP wave. Assume that the waves travel in straight lines, although actual seismic waves follow more complex routes.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
