USE PYTHON TO SOLVE THIS PROBLEM
A bacteria culture grows exponentially. After 2 hours, the bacteria count was 400 cells and after 6 hours, the bacteria count was 20,000 cells.
a) Solve a system of equations to find (approximately) k and y0 (HINT: If will help to assume K is real in the symbols command)
b) Use this to determine when the bacteria count reaches 2,000,000 (exact and approximate).
c) Suppose 400 was the “initial” amount and 20,000 the count after 4 hours. Find k and the approximate amount of bacteria 2 hour BEFORE the “initial” time. In a print statement, explain what you notice when comparing these answers to part a)

((8.27)Q:7)
Two ice skaters, Daniel (mass 70.0 kg ) and Rebecca (mass 45.0 kg ), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 14.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 8.00 m/s at an angle of 55.1 ∘ from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink.
A) What is the magnitude of Daniel's velocity after the collision?
B) What is the direction of Daniel's velocity after the collision?
C) What is the change in total kinetic energy of the two skaters as a result of the collision?

A block weighing 259 g slides along a frictionless track at a
speed 6.1 cm/s. It then attaches to a spring-bumper with an
electromagnetic device so that the block attaches to the bumper.
The bumper has a mass of 130 g, and the spring has a stiffness of
1540 kg/s2 and an equilibrium length of 10.6 cm. After
the spring compresses and returns to its original length, the
magnet turns off and the block launches off again, conserving
energy.
(a) How fast is the block just after it attaches to the
paddle?
(b) What is the maximum compression of the spring before the block
turns around?
(b) How fast is the block moving after it launches off the
paddle?
