you have a two-wheeled trailer that you pull behind your ATV. two children with a combined mass of 70.2kg hop on board for a ride through the woods and the springs (one on each wheel) each compress by 5.97cm. when you pull the trailer over a tree root in the trail, it oscillates with a period of 1.29s. determine the following.
a) force constant of the springs in N/m.
b) mass of the trailer in kg.
c) frequency of the oscillation in Hz.
d) time it takes for the trailer to bounce up and down 10 times in seconds.
