A section of uniform pipe is bent into an upright U shape and partially filled with water, which can then oscillate back and for
th in simple harmonic motion. The inner radius of the pipe is r = 0.011 m. The radius of curvature of the curved part of the U is R = 0.15 m. When the water is not oscillating, the depth of the water in the straight sections is d = 0.21 m.
Write an expression for the mass of water in the tube, in terms of the defined quantities and the density of water, rho. Use the approximation r«R.

Answer:
The magnitude of change in momentum of the ball is and impulse is also
Explanation:
Given:
Velocity of a pitched ball
Velocity of ball after impact
From the formula of change in momentum,
Here mass is not given in question,
Mass of ball is
Change in momentum is given by,
Magnitude of change in momentum is
And impulse is given by
So impulse and
Therefore, the magnitude of change in momentum of the ball is and impulse is also
