Question
A particle undergoes two displacements, mea- sured from the positive x-axis, with counter- clockwise positive. The first has a magnitude of 11 m and makes an angle of 67degrees with the positive x-axis. The resultant displacement has a magnitude of 7.3 m directed at an angle of 105degrees from the positive x-axisA particle undergoes two displacements, mea- sured from the positive x-axis, with counter- clockwise positive.

The resultant displacement has a magnitude of 7.3 m directed at an angle of 105degrees from the positive x-axis
Explanation / Answer
D1 = 11cos67i + 11sin67j
D1 = 4.298i + 10.125j
D2=?
D = 7.3cos105i + 7.3sin105j
D = -1.889i + 7.051j
D = D1 + D2
D2 = -6.187i -3.074j
