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)

A 10.0 gram bullet collides with a motionless 1.00 kilogram block of wood and becomes imbedded in the block. The block is suspended from above by strings which are 1.00 meter long (ignore the mass of the strings). After the collision the block swings to a point where the angle formed by the strings is 25.0 degrees to the vertical. a) what is the potential of the block/bullet combination relative to its original position? b) what is the kinetic energy of the block/bullet combination just after the collision? c) what is the velocity of the block/bullet combination just after the collision? d) what is the velocity of the bullet just before the collision? e) how much work did the bullet do on the block?

((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?
