A 100kg astronaut is fixing a solar panel when his tether breaks and leaves the astronaut drifting 60m from the space station. The astronaut gives a 20N shove over 1.1s to the 8kg tool kit he was carrying (not included in the 120kg mentioned above) in the opposite direction of the space station. How long will it take him to reach the space station? (first calculate the astronaut's acceleration)
