How high will a ball of mass 2 kg thrown with velocity 4 m/s straight up travel before it starts to fall down again? How far will an object of mass 2 kg sliding on a surface with initial velocity 4 m/s travel before it comes to a complete stop, if it experiences a constant friction force of 2 N? If the object in the previous question were to travel twice as fast initially, how much further would it travel before it came to rest? A. It would go 1.4 times as far. B. It would travel the same distance. C. It would travel 4 times as far. D. It would go twice as far.

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

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?
