Answer:
The displacement after 2 seconds is .
Explanation:
The velocity with which the body is projected=20m/s
Then,
The velocity along the x-axis is,
(1)
The velocity along the y-axis is,
(2)
Now, for displacement after 2 seconds for both x and y direction is given as,
Along x-axis
(3)
By substituting the value of and in equation (3) we get;
Along y-axis
(4)
g=acceleration due to gravity=10m/s²
By substituting the value of ,, and g in equation (4) we get;
The net displacement of the particle is,
(5)
By substituting the equations and in equation (5) we get;
Hence, the displacement after 2 seconds is .
