Projectile Motion An astronaut standing on the moon throws a rock upward. The height of the rock is
where s is measured in feet and t is measured in seconds.
(a) Find expressions for the velocity and acceleration of the rock.
(b) Find the time when the rock is at its highest point by finding the time when the velocity is zero. What is the height of the rock at this time?
(c) How does the acceleration of the rock compare with the acceleration due to gravity on Earth?

- 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?arrow_forwardGravity 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.arrow_forwardDistance and Time Anthony leaves Kingstown at 2:00 P.M. and drives to Queensville, 160 mi distant, at 45 mi/h. at 2:15 P.M.
