A64.8 kg astronaut is on a space walk when the tether line to the shuttle breaks. the astronaut is able to throw a 11.0 kg oxygen tank in a direction away from the shuttle with a speed of 10.3 m/s, propelling the astronaut back to the shuttle. assuming that the astronaut starts from rest, find the final speed of the astronaut after throwing the tank. answer in units of m/s.

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
