Two astronauts (both 70 kg) are foating motionless in empty space Far From the Earth. One oF them is
holding a 20kg oxygen tank. He pushes the tank directly toward the second astronaut, who catches and
holds it. IF the speed oF the tank relative to the second astronaut was 2.0 m/sec, then the ±nal speed oF
the second astronaut relative to the ±rst one (aFter the second one has caught the tank) is:
(A) 0.4 m/sec
(B) 0.6 m/s
(C) 1.0 m/s
(D) 1.5 m/s

You are throwing darts at a target, and you notice that the slower you throw the dart, the higher you
have to aim it to hit the center oF the target board. This is because
(A) the slower dart experiences more centripetal Force along its curved arc
(B) the slower dart experiences a stronger gravitational acceleration
(C) the slower dart is a²ected more by air resistance
(D) the slower dart has more time to Fall

. You pull on a car with a rope oF negligible mass, giving the car a small acceleration. The Force oF the rope
on you is
(A) precisely equal in magnitude to the Force oF the rope on the car
(B) less than the Force oF the rope on the car
(C) larger than your pulling Force on the rope
(D) zero.
