Trying to escape Vanessa and Jenny, Joshua runs away down the sidewalk with a velocity of 3.60 m/s and leaps into a wagon that is initially rolling directly towards him at 0.500 m/s.  If Joshua’s mass is 65.0 kg and the mass of the wagon is 80.0 kg, what is the wagon’s final velocity?  Assume that friction is negligible.

A water balloon is thrown straight down with an initial speed of 12.0 m/s from a second floor window, 5.00 m above ground level. If air resistance is negligible, how fast is the balloon moving when it is 0.500 m above the ground?  USE ENERGY CONCEPTS TO SOLVE.

Suppose a 76.0-kg safe is sitting on a wood floor. A robber, whose arm muscles are too puny to lift the safe, attempts to push it across the floor.  If he pushes with a horizontal force of 300.N, will he succeed in moving the crate?  The coefficient of kinetic friction is 0.300, and the coefficient of static friction is 0.500.  Show mathematically, and explain in words, how you reach your answer.

A 65.0 kg skier glides up a 20° slope. Calculate the acceleration of the skier if the coefficient of friction between the skis and snow is 0.100.  

You are on a Ferris wheel at a carnival, seated 10.0 m from the Ferris wheel’s axis. The ferris wheel makes one complete rotation each minute.  Your mass is 60.0 kg. a. What is your angular speed (in SI units)? b. What is your linear speed? c. What is the centripetal force that is exerted on you?

Chromosomes in the chromatin. Centrioles divide.

List the stages of Interphase in order:
