1. A firecracker travels straight up at 75.0m/s and explodes into two pieces. The smaller piece carries one third of the firecracker's mass and shoots off horizontally at 48.0m/s west. Determine the speed and direction of the other piece directly after the explosion. 2. Three blocks slide on a smooth surface. Initially, the first block (m1=1.0kg) moves at 3.0m/s to the right, the second block (m2=2.0kg) is at rest, and the third block (m3=3.0kg) moves to the left at 0.50m/s. First, m1 collides elastically with m2 and recoils to the left. Afterwards, m2 and m3 collide and stick. Calculate, a. the velocities of m1 and m2 after the first collision. b. the velocity of m2 and m3 after the second collision.
5. A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of mass m, moves with velocity (−70 m/s) and a second piece, also of mass m, moves with velocity (−70 m/s). The third piece has mass 3m. (a) Just after the explosion, what is the magnitude of the velocity of the third piece? --------m/s(b) What is the direction of the velocity of the third piece? -----------° counterclockwise from the +x-axis
6. An astronaut in space becomes unteathered from her space craft while tightening bolts on a satellite, and she knows that the conservation of momentum is her only hope to safely get back to her ship. She turns her back to the ship and throws her 3.2-kg wrench in the direction pointing away from the ship. If the astronaut and her space suit have a combined mass of 120 kg and she is able to throw the wrench with a speed of 1.7 m/s, how fast will she move toward the space craft? Hint: you can assume that the astronaut is initially at rest relative to the space craft.
1.Two cars collide at an intersection and stick together. Car A, with a mass of 1200 kg , was going east at vA = 25 m/s before the collision while car B, of mass 1600 kg , was going north at vB = 16 m/s . What is the speed of the cars after the collision? 2.A head-on, elastic collision between two particles with equal initial speed v leaves the more massive particle (mass m1 ) at rest.
