Text solutionVerified
Escape velocity of a projectile from the Earth,
Projection velocity of the projectile,
Mass of the projectile
Let velocity of the projectile far away from the Earth
Total energy of the projectile on the Earth
Gravitational potential energy of the projectile far away from the Earth is zero.
Total energy of the projectile far away from the Earth
From the law of conservation of energy, we have
