A ball of mass 10 kg moving with a velocity `10sqrt3 m//s` along the x-axis, hits another ball of mass 20 kg which is at rest. After the collision, first ball comes to rest while the second ball disintegrates into two equal pieces. One piece starts moving along y-axis with a speed of 10 m/s. The second piece starts moving at an angle of 30 with respect to the x-axis. The velocity of the ball moving at `30^@` with X-axis is x m/s. The configuration of pieces after collision is shown in the figure below.
The value of x to the nearest integer is ______

A ball of mass 10 kg moving with a velocity 10sqrt3 ms^(-1) along X-axis, hits another ball of mass 20 kg which is at rest. After collision, the first ball comes to rest and the second one disintegrates into two equal pieces. One of the pieces starts moving along Y-axis at a speed of 10 m/s. The second piece starts moving at a speed of 20 m/s at an angle theta (degree) with respect to the X-axis. The configuration of pieces after collision is shown in the figure. The value of theta to the nearest integer is "_______"
