When calculating percentage we need two numbers. one number represents total amount of certain thing and another number represents partial number of that thing. then we divide those two numbers.in this problem total amount represents total number of weeds growing on some surface. partial number represents chicory.percentage = partial / total * 100%percentage = 29 / 98 * 100%percentage = 29.6%our calculation is closest to answer b) so this is our correct answer.

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:
