A pronghorn antelope has been observed to run with a tope speed of 97km/h. Suppose an antelope runs 1.5km with an average speed of 85km/h, and then runs 0.80km with an average speed of 67km/h. A) How long will it take the antelope to run the entire 2.3km? B) What is the antelope's average speed during this time?

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

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?
