space a kg, including suit and oxygen tank. The tether line securing the astronaut to their spacecraft loses its attachment from the spacecraft while they are on a spacewalk. The astronaut is initially at rest with respect to the spacecraft, they then throw their 12.0 kg oxygen tank away from their spacecraft with a speed of 8.00 m/s in order to propel themselves back towards it. I) Calculate the maximum distance they can possibly be from the spacecraft and still return within 2.00 min (the amount of time the air in their helmet remains breathable). II) Which of Newton's law of motion explain best why this strategy works? (a) First (b) Second (c) Third

IVIT IN UTES ASK YOUR TEACHER PRACTICE ANUTHER A baseball with a mass of 145 g is thrown horizontally with a speed of 39.7 m/s (89 mi/h) at a bat. The ball is in contact with the bat for 1.15 ms and then travels straight back at a speed of 45.6 m/s (102 mi/h). Determine the average force (in N) exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)
