Hw 6: Momentum 6.1) [6.25 in text book] An astronaut in her space suit has a total mass of 87.0 kg, including suit and oxygen tank. Her tether line loses its attachment to her spacecraft while she's on a spacewalk. Initially at rest with respect to her spacecraft, she throws her 12.0 kg oxygen tank away from her spacecraft with a speed of 8.00 m/s to propel herself back toward it. a) Determine the maximum distance she can be from the craft and still return within 2 minutes (the amount of time the air in the helmet remains breathable).[153.6 m] b) Explain in terms of Newtons's laws of motion why this strategy works.

6.2) [6.40 in text book] A bullet of mas m1 = 8.00 g is fired into a block of mass m2 = 250 g that is initially at rest at the edge of a table of height h = 1.00 m. The bullet remains in the block, and after the impact the block lands d = 2.00 m from the bottom of the table. Determine the initial speed of the bullet.[142.7 m/s]

6.3) [6.54 in text book] Consider a frictionless track as shown in the below figure. A block of mass m1 = 5.00 kg is released from point A. It makes a head-on elastic collision at point B with a block of mass m2 = 10.0 kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision.[0.555 m]

6.4) [6.51 in text book] A billiard ball moving at 5.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.33 m/s at an angle of 30? with respect to the original line of motion. a) Find the velocity (magnitude and direction) of the second ball after the collision[vx2f = 1.25 m/s and vy2f = ?2.165m/s]. b) Was the collision inelastic or elastic?
