Se suelta un cuerpa en caida libre desde cierta altura entonces luego de tres segundos ha recorrido (g-10 m/s2)

The slope of a velocity time graph over any interval of time gives the during that interval

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

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.
