Does the escape speed of a body from the...

Does the escape speed of a body from the earth depend on (a) the mass of the body, (b) the location from where it is projected, (c) the direction of projection, (d) the height of the location from where the body is launched?

Text Solution

Verified by Experts

(a) No, it does not depend on the mass of earth.
(b) No. Gravitational potential depend on the  location, latitude of place. Hence, escape velocity also depend on the location of latitude of place.
(c) No. the escape speed does not depends upon the direction of projection of a body.
(d) Yes, it depends upon the height of the location from where the body is projected because the escape velocity depend upon the gravitational potential at the point from which it is projected and this potential depends upon height also.

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student speculates that the constant C depends on :- (i) The angle at which the ball was launched (ii) The ball's mass (iii) The ball's diameter If we neglect air resistance, then C actually depends on :-
