Two football players kicked the ball from opposite ends of the field which is 100 m long. Player
A kicked the ball with the initial velocity vA0 so that the ball reaches maximum distance. Player B however
kicked with twice the initial velocity of that of player A. Both players kicked the ball simultaneously and both
balls hit the ground at the same time. What is the initial velocity (both magnitude and direction), total time of
flight, and the maximum height that the ball reached in each case?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
