Question

Figure shows a conical pendulum, in which the ball with a mass of m=10.0 kg moves in a horizontal circle at constant speed. If the wire has a length of L=10.0 m and makes an angle of θ=30.0° with the vertical, determine (a) the horizontal (T_x) and vertical (T_y)components of the force exerted by the wire on the ball (b) the radial acceleration of the ball (c) the speed of the ball.
cos30^o =sin60^o=0.866 cos60^o =sin30^o=0.500 g=9.8 m/s²

If C is added to B, the result is -9å + 53 . If B is subtracted from C. the result is 4î – 3. Find
a) unit vector notation of B and C
b) magnitude and direction (the angle between C and positive x axis) of C
c) scalar product of B and C (B. Č).
