- Two masses are held against springs, each are compressed by 25.0 cm. Both are released from rest, travel across the frictionless ground, and stick together when they collide. Find the velocity (magnitude and direction) of both masses right after the collision. m2 = 350 g ki = 42.5 N/m k2 = 30.0 N/m m, = 200 g 25.0 cm 25.0 cm 9.hawkeye shoots an arrow with a mass 35g. the force on the arrow as it is shot through the 25 cm bow is 140f (N) and 0.25 d(m). what is the velocity of the arrow as it leaves the bowAn astronaut floating at rest in space has run out of fuel in her jetpack. She realizes that throwing tools from her toolkit in the opposite direction will help propel her back toward the space station. If the astronaut has a mass of 85 kg and she throws a hammer of mass 4.5 kg at a speed of 4 m/s, what will be the approximate resultant velocity that carries her back to the space station?
- You and another astronaut are in space. You throw a tool to them that has a mass of 15kg. Your mass is 91kg and the other astronaut's mass is 88kg. Initially you and the other astronaut are at rest. You threw the tool at a speed of 8m/s. What is your velocity after you threw the tool?A toy train engine (3.4 kg) is moving 0.25_m/s to the right when it collides with a train car (3.9.kg) moving 0.15 m/s in the opposite direction, and they stick together. Find the velocity of the engine-car combination as they move off together. Assume "to the right" is the positive direction. 0.04319_m/s В. 0.05252_m/s 0.0687_m/s 0.04904 m/s 0.03505_m/s F. А. D. Е. С. 0.0363_m/sA 56.0-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).
- A 10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 20 m/s when a 60 kg skydiver drops out by releasing his grip on the glider. What is the glider's speed just after the skydiver lets go?A 0.19 kg arrow is shot at +42 m/s. It hits an apple (m = 0.62 kg), and goes through the apple, leaving with a velocity of +23 m/s.What is the velocity of the apple after the arrow leaves it?You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 76.3 kg, and the sleds mass is 10.8 kg. The sled is moving by itself on the ice at 3.07 m/s. You parachute vertically down onto the sled, and land gently. What is the sleds velocity with you now on it? 0.49 m/s 0.44 m/s 0.38 m/s 0.23 m/s
- Two clay balls collide and stick. Ball 1 has a mass of 3 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 10 kg and an initial velocity of 12 m/s in the negative x direction. What is the final velocity of the combined mass?A 86-kg astronaut and a 1200-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0.18 m/s directly away from the shuttle. Seven-and-a-half seconds later the astronaut comes into contact with the shuttle What was the initial distance from the shuttle to the astronaut?Express your answer using two significant figures.What is the linear momentum of a 74.0 kg object on the Equator, as measured from the center of Earth? The radius R of Earth is 6371 km.
