From the equation of motion, we know,
Where s= displacement
u= initial velocity
a= gravitational force
t= time
Displacement is 0 since the ball comes back to the same point from where it was thrown.
A = since the ball is thrown upwards.
Plug the known values into the equation.
=>
Solving for u gives :
u= 16.67 m/ sec ....... equation (1)
At maximum height, final velocity i.e v is 0
Time take to reach the top =
=>
Solving for s we get
s= 14.16 m
Answer:
x1=-4/5, x2=18/5 and x3=7/5
Step-by-step explanation:
you can do linear combination between the rows:
2nd row=R2-3R1 and 3th row=R3-2R1
3th row=(3R2-R3)/15
1st row=R1+3R3 and R2-11R3
x1=-4/5, x2=18/5 and x3=7/5
Answer:
The area of a square with side length of 2 inches is 4 square inches.
The area of a circle with radius 1.2 inches is:
That is approximately 4.5 square inches.
Hence, the area of the square (4) is less than {<} that of the circle (4.5)!
