The polar bear is an excellent swimmer, and it spends a large part of its time in the water.Suppose a polar bear wants to swim from an ice floe to a particular point on the shore. The bear dives into the water and begins swimming. As the bear swims, it tires and slows at a rate of 0.0122 m/s/s. By the time it reaches the shore, which is 40.1 m from where it dove into the water, its velocity is 2.13 m/s.How fast was the bear swimming when it first got into the water?
A bath toy is floating stationary in water such that half of the toy is above water and half of the toy is below the water. A kid pulls the toy 3.7 cm down into the water and then lets go. The toy then proceeds to bob up and down. It bobs up and down 16 times in a minute. (a) What is the equation that describes the position of the object at any given time? (b) Where is the toy at time t = 1.41 second (in cm)? Is it mostly above or below the water at this time? Explain.

An object moves in one dimensional motion with constant acceleration a = 7.4 m/s². At time t = 0 s, the object is at x = 3.2 m and has an initial velocity of vo = 4 m/s. How far will the object move before it achieves a velocity of v = 6.6 m/s? Your answer should be accurate to the nearest 0.1 m.
An object moves in one dimensional motion with constant acceleration a = 4.5 m/s². At time t = 0 s, the object is at xo = 2.9 m and has an initial velocity of vo = 4 m/s. How far will the object move before it achieves a velocity of v = 7 m/s? Your answer should be accurate to the nearest 0.1 m.
A cat is sleeping on the floor in the middle of a 3.0 m wide room when a barking dog enters with a speed of 1.50 m/s. As the dog enters, the cat immediately accelerates at 0.85 m/s2 toward an open window on the opposite side of the room. The dog is a bit startled by the cat and begins to slow down at 0.10 m/s2 as soon as it enters the room. How far is the cat in front of the dog as it leaps through the window?
The bacterium Escherichia coli (or E. coli) is a single-celled organism thatlives in the gut of healthy humans and animals.

You throw an object directly up into the air and then catch it when it comes back down. It hits your hand at a speed of 7 m/s on the way down. What was the initial velocity of the ball? Use a kinematic approach.
In kinematics it may be necessary to analyze a situation in which particles do not exhibit regular displacement throughout their movement, so that we cannot use just a mathematical equation to describe their velocity, acceleration and displacement. In cases like these, we use graphs to represent the motion of a particle, since the fundamental equations of speed and acceleration have geometric relationships with the graphs that represent them. Regarding the graphs of acceleration as a function of time, position as a function of time and speed as a function of time, it can be stated that: Choose one:a. The difference between velocities v2 and v1 is numerically equal to the area under the position curve between time t1 and t2, and therefore can be calculated by the derivative: v2-v1 = dS / dt. The difference between the accelerations a1 and a2 is numerically equal to the area under the velocity curve between the time t1 and t2 and can be calculated by the derivative: a2-a1 = dv / dt.B.…
