Initial velocity = Vo= 25 m/s
Final velocity = V = x
Acceleration= a = 6 m/s^2
time= t = 4 seconds
Appy the equation:
V = Vo + at
Replacing:
V = 25 + 6(4) = 25 + 24 = 49 m/s

Answer:
Explanation:
Given
Initial velocity of ball 
height of window 
Using Equation of motion
where u=initial velocity
t=time
a=acceleration
As ball is already is at a height of 20 m so
(b)highest point is obtained at v=0
where
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Highest Point will be 
(c)Time taken when the ball hit the ground i.e. at Y=0
impact velocity 
<h2>Answer:</h2>
<u>The statement is </u><u>False</u>
<h2>Explanation:</h2>
Contaminated rags may contain plastic and other materials that cannot be defused in soil and they remain there for a long period of time. Another reason to avoid disposal of contaminated material in earth is that it may also contain toxic materials which may result into land pollution. So it is not recommended to dispose contaminated rags in landfills.
