Flying Circus of Physics In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 59 m/s (terminal speed), that his mass (including gear) was 67 kg, and that the magnitude of the force on him from the snow was at the survivable limit of 1.2 × 105 N. WWhat are (a) the minimum depth of snow that would have stopped him safely and (b) the magnitude of the impulse on him from the snow? (a) Number i Units (b) Number i Units

A 0.27 kg softball has a velocity of 11 m/s at an angle of 34° below the horizontal just before making contact with the bat. What is the magnitude of the change in momentum of the ball while it is in contact with the bat if the ball leaves the bat with a velocity of (a)17 m/s, vertically downward, and (b)17 m/s, horizontally back toward the pitcher? (a) Number Units (b) Number i Units
