The force required to stretch a Hooke’s-law spring varies from 0 N to 75.2 N as we stretch
the spring by moving one end 13.6 cm from
its unstressed position.
1.) Find the force constant of the spring.
Answer in units of N/m.
2.) Find the work done in stretching the spring.
Answer in units of J.

Does this organism still meet the definition of a eukaryote ? why or why not?

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?

Who was the first scientist to measure speed as distance over time?
