Lucy and her friend are working at an assembly plant making wooden toy giraffes. At the end of
the line, the giraffes go horizontally off the edge of
a conveyor belt and fall into a box below. If the box
is 0.60 m below the level of the conveyor belt and
0.40 m away from it, what must be the horizontal
velocity of giraffes as they leave the conveyor belt?

Write the function getkthdigit(n, k) that takes a possibly-negative int n and a non-negative int k, and returns the kth digit of n, starting from 0, counting from the right

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
