**Problem 83.** The central attractive force \( F \) on an earth satellite can have no moment about the center \( O \) of the earth. For the particular elliptical orbit with major and minor axes as shown, a satellite will have a velocity of \( 33{,}880 \text{ km/h} \) at the perigee altitude of \( 390 \text{ km} \). Determine the velocity of the satellite at point \( B \) and at apogee \( A \). The radius of the earth is \( 6371 \text{ km} \).**Diagram Explanation:**The diagram illustrates an elliptical orbit around the Earth. The Earth is shown as a circle at the center labeled \( O \). The elliptical orbit is represented as an elongated dashed circle surrounding the Earth. Key points labeled on the elliptical orbit include:- **Perigee \( P \)**: The point where the satellite is closest to the Earth. The velocity at this point is given as \( 33{,}880 \text{ km/h} \) and the altitude above Earth at this point is \( 390 \text{ km} \).- **Apogee \( A \)**: The point where the satellite is farthest from the Earth. The distance from Earth's center to this point is shown as \( 13{,}520 \text{ km} \).- **Point \( B \)**: Positioned at a different location on the elliptical path with a vertical distance of \( 11{,}720 \text{ km} \) from the center.The overall geometry demonstrates the varying distance of the satellite from Earth at different orbital positions, which affects its velocity due to gravitational attraction.

An object of mass m1 slides on a sloped block of mass M2, which in turn slides on a horizontal surface. The slope angle is a constant 3, and both masses are initially at rest. There is no friction between any of the objects, and the masses are subject to the force of gravity -mgêy. Use as co- ordinates the horizontal position x2 of mass m2, and the height y1 of mass m1, as shown in the y4 Y1 M2 x2 diagram to the right. Find the equation of motion of block 2, ä2(t).
