What is the magnitude of the impulse component that is perpendicular to the wall? [J = -2.5 kgm/s] 8. A 35.0 g bullet is traveling nearly horizontally at 465 m/s. It ricochets off a piece of metal lying on the ground, such that piece of the angle of reflection is 85.0 (angle with respect to the piece of metal is 5.00). How much force does the metal apply to the metal if the time of contact is 0.0260 s and there is no change in speed? [J = 2.8369 kgm/s; F=109 N] 9. A turbine requires an impulse of 1250 kgm/s in order to begin spinning. The blade angles are fixed, such that the angle of reflection is 65.0. If the maximum velocity of gas molecules striking the turbine is 150. m/s, what mass of gas molecules is needed to make the turbine spin? [9.86 kg]
