A wood block of mass niw = 200 g is projected from the ground at a speed vn= 35 m/s and at an angle & = 50°. When at height It = 24 m the wood block was hit by a bullet of mass mb = 25 g which was moving at ih = 220 m/s and at an angle Oh = 70°. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has coefficient of kinctic friction µi = 0.5 and start to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3x10? N/m. Right end of the spring is fixed, and all motions are confincd in x-y plane.
