The positive x-axis is directed from her initial to her final position and the positive y-axis is directed vertically upwards -ag 33% Part (a) Eater an expression for the jumpers initial velocity vector in terms of, md ed 33% Part (b) Calculate the maximum height, in meters, that the jumper reaches above ground level o 725148 0.7251 Correct 33% Part (c) what r position, n meters, did de juaper begin her long jump? to- sin) coso tun) x cotan) asin) acos

Explanation / Answer

a)

V= (vo cos (theta) ) i + (vo sin (theta)) j

=======

c)

x= vo^2 sin (2* theta)/g= 5.75^2* sin 2*41)/9.8= 3.341 m

=======

Comment in case any doubt.. good luck
