Motion In A Plane

Question

A particle starting from the origin (0,0) moves in a straight line in the (x,y) plane. Its coordinates at a later time are ( $square root of 3 comma space 3$ ). The path of the particle makes with the x -axis an angle of:

30^o

45^o C

60^o C

0⁰

Solution

60^o C

The slope of the path of the particle gives the measure of angle required.

Draw the situation as shown. OA represents the path of the particle starting from origin O (0,0). Draw a perpendicular from point A to X- axis. Let path pf the particle makes and angle θ with the x -axis, then
tan θ = slope of line OA

$AB over OB space equals space fraction numerator 3 over denominator square root of 3 end fraction space equals space square root of 3 theta space equals space 60 to the power of 0$
