una particula oscila con M. A.S de 20 cm de amplitud y 1.8 s de periodo calcula la elongacion ,velocidad y aceleracion cuando ha trancurrido un sexto de periodo

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
