Answer:
v/U=0.79
Explanation:
Given u=
Now for the given flow to be possible it should satisfy continuity equation
Applying values in this equation we have
Thus we have
Hence proved
For maximum value of v/U put y =
Thus solving we get using the given values
v/U=0.79
D A little longer than a yard (about 3 ft)
Answer:4 times
Explanation:
Given
Balls are identical and thrown with initial velocity lets say u and 2u because the other ball is thrown with twice the velocity of first
Maximum height reached by first ball is h which is given by
For second ball
Thus height gained by second ball will be 4 times of first ball.
