A particle is fired vertically upward with a speed `v_(0)`. Find
(a) Speed at distance `2R_(e)` from centre of earth.
(b) Calculated maximum height attained by particle.

A particle of mass m is fired vertically upward with speed v_(0) (v_(0) lt " escape speed ") . Prove that (i) Maximum height attained by the particle is H = (v_(0)^(2)R)/(2gR - v_(0)^(2)) , where g is the acceleration due to gravity at the Earth's surface and R is the Earth's radius . (ii) When the particel is at height h , the increase in gravitational potential energy is (mgh)/(1+h/R)

A particle is thrown vertically upward with speed 40 m//s . (a) After how much time attains maximum height? (b) Find (i) the maximum height attained by the particle. (ii) the velocity at half of the maximum height. (c ) Find (i) the ratio of distances in the first half and the next half of time. the ratio of the time in the first half and the second half of the distance (consider only upward journey)
