A projectile of mass `m` is fired from the surface of the earth at an angle `alpha = 60^(@)` from the vertical. The initial speed `upsilon_(0)` is equal to `sqrt((GM_(e))/(R_(e))`. How high does the projectile rise ? Neglect air resistance and the earth's rotation.

A body is lauched from the earth's surface a an angle alpha=30^(@) to the horizontal at a speed v_(0)=sqrt((1.5 GM)/R) . Neglecting air resistance and earth's rotation, find the height to which the body will rise.

A projectile is fired from surface of earth at 30^(@) above horizontal with speed u=sqrt((GM_(c))/(R)) where M_(c) is mass of earth R is radius of earth Find maximum height of the projectile above earth surface

A projectile is to be launched from the surface of the earth so as to escape the solar system. Consider the gravitational force on the projectile due to the earth and the sun nly. The projectile is projected perpendicular to the radius vector of the earth relative to the centre of the sun in the direction of motion of the earth. Find the minimum speed of projection relative to the earth so that the projectile escapes out of the solar system. Neglect rotation of the earth. mass if the sum M_(s)2xx10^(30)kg, Mass of the earth M_(e)=6.4xx10^(24)kg Radius if the earth R_(e)=6.4xx10^(6)m, Earth- Sun distence r=1.5xx10^(11)m

A rocket of mass M is launched vertically from the surface of the earth with an initial speed V= sqrt((gR)/(2)) . Assuming the radius of the earth to be R and negligible air resistance, the maximum height attained by the rocket above the surface of the earth is (R)/(X) where X is:
