A projectile is fired straight upward from Earth’s surface with a speed that is half the escape speed. If R is the radius of Earth, the highest altitude reached, measured FROM THE SURFACE, is: 1. R/3 2. 2R 3. R/4 4. R 5. R/2

Step 1
The escape speed \( v_e \) is given by the formula: \[ v_e = \sqrt{\frac{2GM}{R}} \] where \( G \) is the gravitational constant, \( M \) is the mass of Earth, and \( R \) is the radius of Earth. Show more…

A projectile is launched from Earth with a velocity that is just one-half of the velocity it will take to escape. The escape velocity for such a projectile is given by: v_escape = sqrt(2GME/RE). Of the following, which one gives the maximum distance from the center of Earth that the projectile will reach? A. R = 4/3 RE B. R = 3/2 RE C. R = 2RE D. R = 4RE

A rocket is launched with velocity $10 \mathrm{kms}^{-1}$. If radius of earth is $R$ then maximum height attained by it will be = (A) $2 \mathrm{R}$ (B) $3 \mathrm{R}$ (C) $4 \mathrm{R}$ (D) $5 \mathrm{R}$
A projectile is launched vertically upward from a planet of mass $M$ and radius $R ;$ its initial speed is $\sqrt{2}$ times the escape speed. Derive an expression for its speed as a function of the distance $r$ from the planet's center.
