An average person can reach a maximum height of about 65 cm when jumping straight up from a crouched position. During the jump i
tself, the person's body from the knees up typically rises a distance of around 48 cm. To keep the calculations simple and yet get a reasonable result, assume that the entire body rises this much during the jump.A) With what initial speed does the person leave the ground to reach a height of 65 cm? andb)In terms of this jumper's weight W , what force does the ground exert on him or her during the jump?
