A body is projected vertically upward with speed vo(Vo Vescape) from surface of earth. The speed of body at h height is (where Ris radius of earth and g is acceleration due to gravity at earth's surfa

Q. A body is projected vertically upwards from the surface of earth with a velocity equal to half the escape velocity. If $R$ is the radius of the earth, maximum height attained by the body from the surface of earth is

Q. A body is projected vertically upwards from the surface of the earth with a velocity equal to ${\frac{3}{4}}^{th}$ escape velocity of earth. If ${}^{\prime }{R}^{\prime }$ is the radius of earth, the maximum height attained by the body is:

Q. An object is projected vertically upward with speed $\sqrt{gR},$ where R is radius of earth and g is acceleration due to gravity on surface of earth, Find the maximum attained by it.

Q. A body is projected from the ground vertically upwards with a speed of 4 km/s. How high will it rise ? Neglect air resistance. (Radius of the earth = 6400 km, Acceleration due to gravity $=9.8m/s^2$

Q. A particle is projected vertically upward from the surface of the earth with a speed of $\sqrt{\frac{3}{2}gR}$, $R$ being the radius of the earth and g is the acceleration due to gravity on the surface of the earth. Then the maximum height ascended is (neglect cosmic dust resistance)
