In a game of pool the cue ball is moving with an initial velocity of 4 m/s when it collides elastically with the 8 ball initially at rest. The cue ball moves off at an angle of 30 degrees with respect to it original direction after the collision and the 8 ball moves off at an angle of 60 degrees with respect to the original direction. If the two balls have the same mass find the final speed of both balls after the collision.
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
