Problem 2 A deformable object with mass of 30-kg is traveling toward a rigid structure at 2000 km/hr as shown in the figure below. After striking the structure is leaves at a speed of 600 km/hr as shown. Determine the magnitude and direction of the average impulsive force generated in the collision if it last 500 ms. 30° 2000 km/hr 20 600km/hr
Q6. As shown in the image below, the spring (with spring constant k = 2.4 kN/m) is fixed to block A, and block B is pressed against the spring. The masses of blocks A and B are mÃ = 19 kg and m² = 15 kg, respectively. The spring is initially compressed by 240 mm, and then both blocks are released from rest. Determine the velocity of block A at the instant block B loses contact with the spring. Right is considered the positive direction and negative sign must be included if the velocity points to the left. (Hint, neglect friction, and since there is no impulsive force, energy is conserved.) Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit. Your Answer: Answer A www k units B
