A 85.0-kg astronaut is in space, far from any objects that would exert a significant gravitational force on him. He would like to move toward his spaceship, but his jet pack is not functioning. He throws a 0.720-kg socket wrench with a velocity of 5.00 m/s in a direction away from the ship. After 0.500 s, he throws a 0.800-kg spanner in the same direction with a speed of 8.00 m/s. After another 9.90 s, he throws a mallet with a speed of 6.00 m/s in the same direction. The mallet has a mass of 1.20 kg. How fast is the astronaut moving after he throws the mallet?(assume all speeds are relative to the spaceship). m/s Assignment i Saved Help Save & Ex Required information Required information he point (x, )) = (25.0 cm, 2.30 cm). ass of 5.40 g and particle B has a mass of 2.40 g.

The two cars couple together on collision. What is the x-component of the CM? cm What is the speed of the two cars after the collision? m/s ! Required information Required information In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.10 m/s and collides with an initially stationary, fully loaded boxcar of mass 4.60m. The two cars couple together on collision. Particle A has a mass of 5.40 g and particle B has a mass of 2.40 g. Particle A is located at the origin and particle B is at the point (x, y) = (25.0 cm, 2.30 cm). Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.10 m/s? What is the y-component of the CM? cm PhotoGrid Check my A 2.20-kg block is moving to the rig moving to the right at 1.60 m/s just before it strikes and sticks to a 1.00-kg block initially at rest. What is the total momentum of the two blocks after the collision? Enter a positive answer if the total momentum is toward right and a negative answer if the total momentum is toward left. For a system of three particle system? Enter a positive value if the vel g a line, an observer in a laboratory measures the following masses and velocities. What is itive value if the velocity of the CM of the system is in the +x direction and enter a kg.m/s "coative value if the velocity of the CM of the system is in the -x direction. Mass (kg) Vx (m/s) 5.0 2 120 2.0 m/s
