Question
A truck with a boom attached is accelerating on a straight path with a velocity of 10 m/s and an acceleration
of 1 m/s². The initial length of the boom is 5 m and it has an angle of 60°^with the horizontal. The driver
starts to retract the boom with radial acceleration of 1 m/s² and lowers it with an angular acceleration of
0.5 rad/s². Meanwhile another vehicle moves in the opposite direction with a velocity of 20 m/s. The
initial horizontal distance between them is 30 m. For the instant when the two vehicles meet
a) Determine the absolute velocity and acceleration of the boom tip.
b) Determine the relative velocity of the boom tip with respect to the other vehicle.
