Consider a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket’s position measured from the center of the Earth is given by:<\/p>\n

\"01\"<\/p>\n

where RE<\/sub> is the radius of the Earth (6.38 \u2715 106<\/sup>m) and g is the constant acceleration
\nof an object in free fall near the Earth’s surface (9.81 m\/s2<\/sup>).<\/p>\n

(a) Determine expressions for velocity and acceleration of the rocket
\n(b) When will the rocket be at \"y = 4R_{E}\" ?
\n(c) What are the velocity and the acceleration when \"y = 4R_{E}\" ?<\/p>\n

Solution:<\/strong><\/h2>\n

(a) Velocity of the rocket is<\/p>\n

\"02\"<\/p>\n

Acceleration of the rocket is<\/p>\n

\"03\"<\/p>\n

(b) When \"y = 4R_{E}\"<\/p>\n

\"04\"<\/p>\n

(c) The velocity of the rocket when \"y = 4R_{E}\" or \"\frac{7}{3}\sqrt{\frac{2R_{E}}{g}}\" is<\/p>\n

\"v_y = \frac{R_E\sqrt{2g}}{(R_E^{3/2} + 3\sqrt{\frac{g}{2}}R_E * \frac{7}{3} \sqrt{\frac{2R_{E}}{g}})^{1/3}} = \frac{R_E\sqrt{2g}}{(8R_{E}^{3/2})^{1/3}} = \sqrt{\frac{gR_{E}}{2}} (m/s)\"<\/p>\n

The acceleration of the rocket when \"y = 4R_{E}\" or \"t = \frac{7}{3} \sqrt{\frac{2R_{E}}{g}}\" is<\/p>\n

\"05\"<\/p>\n

Answers:<\/strong><\/h2>\n

(a) \"06\"<\/p>\n

(b) \"07\"<\/p>\n

(c) \"08\"<\/p>\n
