An astronaut on the moon throws a baseball upward. The astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 50 ft per sec. The height s of the ball in feet is given by the equation s =-27t2 + 50t+ 6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b. a. After how many seconds is the ball 18 ft above the moon's surface?

2. Artificial gravity is necessary for humans to stay healthy during extended stays in space. To provide artificial gravity, a space station is shaped like a cylinder with a diameter of 2200 m, and it rotates about its center at a constant rate. The astronauts live inside the cylinder at the outer edge, and feel a gravitational pull outwards. (a) How long should one revolution of the space station take if the acceleration of an astronaut on the outer edge...

A student at the top of a building throws a red ball upward with speed v0 and then throws a blue ball downward with the same initial speed v0. Immediately before the two balls reach the ground, which of the following statements are true? (Select all that apply.) A. The acceleration of the blue ball is greater than that of the red ball. B. The speed of each ball is greater than v0. C. The speed of the red ball...

A blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 0.5 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.5 m/s from a height of 31.5 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. How long after the blue ball is...
