Question

9 of 10 PartA Find the magnitude of the vector A-(6.1 m (30 m . Express your answer using two significant figures. A5.1 m Previous Answers Correct Here we learn how to determine the magnitude of a vector with given z and y components Part B Find the direction of the vector A-(5.1+(0.30 m )ý Express your answer using two significant figures. A-360 counterclockwise from the +2-axis Correct Here we learn how to determine the direction of a vector using its z and y components MacBook Air 1 4) 40)) F7 F8 F9 F11 F12

Explanation / Answer

here,

F)

A = 5.1 i m - 0.3 j m

B = - 0.3 i m + 5.1 j m

R = A + B

R = 5.1 i m - 0.3 j m + (- 0.3 i m + 5.1 j m )

R = 4.8 i m + 4.8 j m

direction of R , theta = arctan(4.8/4.8) = 45 degree above positive x-axis
