The Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?
Distance and time Anthony leaves Kingstown at 2:00 PM and drives to Queenville, 160 mi distant, at 45mi/h .At 2:15 PM. Helen leaves Queensville and drives to Kingstown at 40 mi/h . At what time do they pass each other on the road?
Air Temperature As dry air moves upward, it expand and, in so doing, cools at a rate of about 1°C for each 100-meter rise, up to about 12 km. (a) If the ground temperature is 20°C, write a formula for the temperature at height h. (b) What range of temperatures can be expected if an air plane lakes off and reaches a maximum height of 5 km?
Shadow Length A person who is 6 feet tall walks away from a 50-foot tower toward the tip of the tower’s shadow. At a distance of 32 feet from the tower, the person’s shadow begins to emerge beyond the tower’s shadow. How much farther must the person walk to be completely out of the tower’s shadow?
Height of a Ball If a ball is thrown directly upward with a velocity of 40 ft/s, its height (in feet) after t seconds is given by y=40t16t2 . What is the maximum height attained bythe ball?
Gravity If an imaginary line segment is drawn between the centers of the earth and the moon, then the net gravitational force F acting on an object situated on this line segment is F=Kx2+0.012K(239x)2 Where K0 is a constant and x is the distance of the object from the center of the earth, measured in thousands of miles. How far from the center of the earth is the dead spot where no net gravitational force acts upon the object? Express your answer to the nearest thousand miles.
Maximum height of Projectile A stone is thrown upward from the top of a building. Its height in feet above the grouond after t seconds in given by ht=-16t2+48t+32 What maximum height does it reach?
Relativistic Length A rocket ship travelling near the speed of light appears to a stationary observer to shorten with speed. A rocket ship with a length of 200 meters will appear to a stationary observer to have a length of 2001-r2 meters, where r is the ratio of the velocity of the ship to the speed of light. What is the apparent length of the rocket ship if it is travelling at a speed that is 99% of the speed of light?
Flagpole Height A person who is 6 feet tall walks away from a flagpole toward the tip of the shadow of the flagpole. When the person is 30 feet from the flagpole, the tips of the person’s shadow and the shadow cast by the flagpole coincide at a point 5 feet in front of the person. (a) Draw a diagram that gives a visual representation of the problem. Let h represent the height of the flagpole. (b) Find the height of the flagpole.
