(11%) Problem 4: Suppose you first walk 10.5 m in a direction 20° west of north and then 25 m in a direction 40 south of west as shown in the figure 40° ssignment Status 20° Click here for detailed view oblem Status Otheexpertta.com leted Completed 3 Completed 25% Part (a) what is the component of vour displacement in the x-direction in meters Grade Summary Deductions 10096 acos0 (506 per attempt) e Degrees Radians I give up Hints al 2500 Part (b) What is the component of your displacement in the y-direction, in meters? EI A 25% part (c) How far are you tom your starting point In meters

Explanation / Answer

here,

first displacement , d1 = 10.5 * ( - sin(20) i + cos(20) j) m

d1 = - 3.59 i m + 9.87 j m

seccond displacement , d2 = 25 * ( - cos(40) i - sin(40) j ) m

d2 = - 19.2 i m - 16.1 j m

a)

the x component of displacment , Rx = - 22.79 m

b)

the y component of displacement , Ry = - 6.23 m

c)

the distance from the starting point , R = sqrt(Rx^2 + Ry^2)

R = 23.6 m
