Answer to Question #35948 in Mechanics | Relativity for shreyansh anand
A ball kept on a wall is pushed horizontally with
certain velocity and allowed to move under gravity. Such a
motion is two-dimensional motion with ball covering
displacements in both x and y-directions. But both the x & y
direction motions are independent of each other. Hence,
motion in x-direction can be considered as similar to straight
line motion with no acceleration. Motion in y-direction can be
considered as free fall under gravity.
In the figure shown, ball is pushed horizontally from a
height of 19.6 m, with initial velocity as 10 m/s
[Take g = 9.8 m/s2]
10. The horizontal displacement of projectile after 1 sec.
