Gr. 11 Physics (Univ. Prep.) 9. Flossy the astronaut on the moon throws a wrench straight up at 4.0 m/s. Three seconds later it is falling downwards at a velocity of 0.80 m/s. a) What was the acceleration of the wrench after it left the Flossy's hand? (1.6 m/s2 [down]) b How high above the point from which it was released was the wrench at 3.0 s?(4.8 m [up]) How long would it take the wrench to return to the position from which it was thrown.? (5.0 s) 10. At Los Alamos National Laboratory in New Mexico, protons are accelerated from rest to a velocity
