a) A space vehicle is launched vertically upward from the Earth's surface with an initial speed of 8.90 km/s, which is less than the escape speed of 11.2 km/s. What maximum height does it attain? Your response differs from the correct answer by more than 10%. Double check your calculations. m (b) A meteoroid falls toward the Earth. It is essentially at rest with respect to the Earth when it is at a height of 2.35 107 m above the Earth's surface. With what speed does the meteorite (a meteoroid that survives to impact the Earth's surface) strike the Earth? m/s

Need people build a dam to create a reservoir that supplies water a nearby city needs. describe two ways this action will likely affect the water cycle in the local environment. (5 points) worth 20 points

What’s #16 asking and how do i solve it?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
