An object is thrown upward with a velocity of 40 m/s-1. Calculate the maximum height attained by the object take the gravity to be 10m/s-2

V²=u²+2as

40²=0+2(10)s

1600/20 =20s/20

s=80

the max height is 80m

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
