36. A 3000 kg truck moving at 17 m/s collides with a stationary 1600 kg passenger car, and the two stick together. Assuming that they are free to move afterward, what is the momentum of the truck+car object after the collision? 78000 kg m/'s 51000 kg m/'s 27000 kg m/'s 18000 kg m/'s 11 kq m/'s 37. A steel ball traveling at 6 m/'s hits a stationary line ofthree steel balls. Which statementis true if the collision is perfectly elastic? The original ball stops and a single ball moves to the right at 6 m/s. All four balls move to the right at 15 m/s The original ball bounces back at -3 m/'s and one ball moves to the rightat +3 m/s. The original ball stops and two balls move to the right at3 m/s. The original ball bounces back at-6 m/'s and one ball moves to the rightat +6 m/'s 38. A 0.5-kg ball moving at 5 m's strikes a wall and rebounds in the opposite direction with a speed of 2 m's. If the impulse occurs for a time duration of 0.01 s, find the average force (magnitude only) acting upon the ball 39. A 0.540 kg basketball hits a wall head-on with a forward speed of 160 mi's. It rebounds with a speed of 13 m/'s. The contact time is 0.100 seconds. a) determine the impulse with the wall, b) determine the force of the wall on the ball. 40. A 4.0 kg object has a forward velocity of 20.0 m/'s. A resistive force of 6.0 Nimpedes is motion for 8.0 seconds. Determine the final velocity of the object. Al. In a physics lab, a 0.500-kg cant moving at 36 4 cm's collides inelastically with a second cart which is initially at rest. The two carts move together with a speed of 21.8 cm's after the collision. Determine the mass of the second cart
