Problem
A body is projected at time t=0 from a certain point on a planet's surface with a certain velocity at a certain angle with the planet's surface, assumed horizontal. The horizontal and vertical displacements x and y, in metres, respectively vary with time t, in seconds, as x=(103)t and y=10t−t2. The maximum height attained by the body is
(1) 75 m
(2) 100 m
(3) 50 m
(4) 25 m
