A2000 kg car moves down a level highway under the actions of two forces. one is a 1060 n forward force exerted on the drive wheels by the road; the other is a 1010 n resistive force. use the work-energy theorem to find the speed of the car after it has moved a distance of 21 m, assuming it starts from rest.

What is hidden during a lunar eclipse? isn't the moon hidden?

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?

Sound is a disturbance that travels through a medium as a
