3. In the air track experiment, a glider of mass m1 = 0.150 kg moving with initial speed of 0.571 m/s along the +x-direction collides with another glider of mass m2 = 0.375 kg initial at rest in an elastic collision. Ignoring any frictional forces, what are the final velocities of the two gliders?

Which changes of state do the labels represent? a: b: c:

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
