The potential energy is 75 × 10¹⁰ Joule and kinetic energy is 1.5 × 10¹² Joule.
Explanation:
Mass of the Rocket,m = 3×10⁶ kg
Velocity = 1 km/s = 1000 m/s
Altitude,h= 25 km = 25×1000 m
=25000 m
(a)Potential Energy = mgh
=3 × 10⁶ × 10 × 25000
= 75 × 10¹⁰ Joule
(b) Kinetic Energy = 1/2 mv²
=1/2 × 3 × 10⁶ × (1000)²
= 1.5 × 10¹² Joule
Hence the potential energy is 75 × 10¹⁰ Joule and kinetic energy is 1.5 × 10¹² Joule.
