A rod of mass m =2.4 kg and length d =2 m can rotate in a vertical plane about a

horizontal axis passing through its center and directed towards the reader. At time t =

0 s the rod is stationary in a horizontal position. A point mass with mass m=0.5 kg

falls vertically from a height h and strikes the rod at a distance r =0.8 m from its center,

sticking to it (Figure 1). If the initial velocity of the point mass is zero, calculate how

large h must be for the rod and the point mass to be able to make a rotation of 270

.

There is no friction in the rotational motion.
