The United States possesses the ten largest warships in the world, aircraft carriers of the Nimitz class. Suppose one of the ships bobs up to float 11.0 cm higher in the ocean water when 50 fighters take off from it in a time interval of 25 min, at a location where the free-fall acceleration is 9.78 m/s2. The planes have an average laden mass of 29 000 kg. Find the horizontal area enclosed by the waterline of the ship.
In Example 4.6, we investigated the apparent weight of a fish in an elevator. Now consider a 72.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.20 m/s in 0.800 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.50 s and comes to rest. What does the spring scale register (a) before the elevator starts to move, (b) during the first 0.800 s, (c) while the elevator is traveling at constant speed, and (d) during the time interval it is slowing down?
Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 92.9 kg, down a theta= 79.4º slope at constant acceleration a=-1.7 m/s2, as shown in Figure (here we assume the positive direction is going down the slope. So the given acceleration is a negative value, it means its direction is going up the slope, slowing down as it moving downward). So The coefficient of friction between the sled and the snow is 0.100. How many Joules of work is done by the tension in the rope as the sled moves 9.1 m along the hill? Use g= 10 m/s2. Your answer for this problem maybe some large number. Just put in the raw number as your answer. For example, 34567.11. But remember you have to specify if the work is positive or negative, if it is negative, you need to input, for example, -34567.11
Paleontologists estimate that if a Tyrannosaurus rex had tripped and fallen, the ground would have exerted anormal force of approximately 260,000 N on its torso as it landed.Assuming the torso has a mass of 3800 kg, (a) find the magnitudeof the torso’s upward acceleration as it comes to rest. (For comparison, humans lose consciousness with an acceleration of about 7g.)(b) Assuming the torso of a T. rex is in free fall for a distance of 1.46m as it falls to the ground, how much time is required for the torsoto come to rest once it contacts the ground?
Two objects of the same mass are sliding at the sameinitial speed across a wooden surface.

In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.
Two masses in an Atwood machine are 3.3 kg and 14.9 kg, the vertical distance of the heavier body being 56.5 cm above the lighter one when they were hold stationery by student. However when they were suddenly released, what would be their common acceleration (m/s^2) ?
An adventurous archaeologist crosses between two rock cliffs, with a raging river far below, by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope. The rope will break if the tension in it exceeds 3.00 x 104 N, and our hero’s mass is 81.6 kg. If the angle that the rope makes with the cliff is 75o, find the tension in the rope. What is the smallest value the angle can have if the rope is not to break?

Consider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.47 m/s2 and the person has a mass of 98.1 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.
