Question

Soldiers marching in formation reach the edge of a grassy field and encounter mi speed drops from 1 meter/sec to 0.5 meters/sec. If they hit the edge of the field at an angle of 30 degrees, W ud as shown in the figure below angle do they end up marching at in the mud in order to stay in formation? Grass 30 degrees Mud

Answer 1

The ratio of speed in grass to the speed in mud is 1/0.5= 2

So if they hit the edge of the field at an angle of 30 degrees, and the angle they do end up marching at in the mud in order to stay in formation be theta,

1*sin(30)= 2*sin(theta)

So, theta= 14.47 degrees. So the angle they do end up marching at in the mud in order to stay in formation is 14.47 degrees.
