Question

A ball is projected from a certain point on the surface of a planet at a certain angle with the horizontal surface The horizontal and vertical displacement x and y varies with time t in second as: x = 10root3t and y = 10t -t ^2
The maximum height attained by the ball is
(A) 100 m
(B) 75 m
(C) 50m
(D) 25 m.

Answer 1

Answer:

a ball is projected from a certain point on the surface of a Planet at a certain angle with the horizontal surface. the horizontal and vertical displacement X and Y vary with time t in second as : x=10√3 and y=10t-t^2 .
