An asteroid, named Toutatis, is in a near Earth orbit. The asteroid is 5.4 km in diameter, more precisely it is 4.6 km x 2.4 km x 1.9 km. The asteroid has a mass of 0.05 x 1015 kg. If the path of the asteroid is assumed circular around the Sun, the radius of the orbit is 2.38 x 10 m and it takes 3.98 years to make one orbit, how much kinetic energy does it carry? If it collided with Earth, where would this energy go? If we could divert the asteroid by exploding a nuclear bomb on its surface that had an energy yield of 0.01% of its kinetic energy, how big would the nuke have to be in Mtons, where 1 Mton = 4.2 x 1015 J?

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?
