Robots have such a one track mind that when they encounter a problem that they aren't programed for they just stare off into space, humans are the better choice in my opinion.

My question is this, ok say that a different kind of primate evolved instead of the one that we evolved from, would that different primate species contribute to having different physical attributes and appearance?

People think I'm weird when I say I can smell the different seasons. They say seasons don't have a smell.

Consider a air-tight box which has insects(100000 of them) inside it. The box without insects weigh 100 kgs. (say). The box considered i.e the box with insects inside it weigh 200 kgs.(say). Now, if all the insects inside the box starts flying, does the weight of the box (i.e. 200 kgs) change?
Note: Consider that the box is weighed after a considerable amount of time with the insects flying inside the box.

Two basketball players are essentially equal in all respects. (They are the same height, they jump with the same initial velocity, etc.) In particular, by jumping they can raise their centers of mass the same vertical distance, (called H their "vertical leap"). The first player, Arabella, wishes to shoot over the second player, Boris, and for this she needs to be as high above Boris as possible. Arabella jumps at time , and Boris jumps later, at time (his reaction time). Assume that Arabella has not yet reached her maximum height when Boris jumps.



1)Find the vertical displacement , D(t) = H(a)(t) - H(b)(t) as a function of time for the interval 0 < t < t(r) , where H(a)(t) is the height of the raised hands of Arabella, while H(b)(t) is the height of the raised hands of Boris.
Express the vertical displacement in terms of H, g , and t.

i found out that:

x(man)t(catch)=x(bus)t(catch)

and

-b+ct(catch)=(1/2)at^2(catch)

A man is running at speed c (much less than the speed of light) to catch a bus already at a stop. At t=0 , when he is a distance b from the door to the bus, the bus starts moving with the positive acceleration a .
Use a coordinate system with x=0 at the door of the stopped bus.

So,

What is the minimum value of c for which the man will catch the bus?

Express the minimum value for the man's speed in terms of a and b ?

PLEASE clear explanations...thanks
