You have a two-wheel trailer that you pull behind your atv. two children with a combined mass of 76.2 kg hop on board for a ride through the woods and the springs (one for each wheel) each compress by 6.17 cm. when you pull the trailer over a tree root in the trail, it oscillates with a period of 2.09 s. determine the following. (a) force constant of the springs? n/m

(b) mass of the trailer? kg

(c) frequency of the oscillation? hz

(d) time it takes for the trailer to bounce up and down 10 times? s

the answer is 3.1 his answer is wrong mines is right

i believe the answer would be:

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
