70. ||| A water pipe in a building delivers 1000 liters (with mass 1000 kg) of water per second. The water is moving through the pipe at 1.4 m/s. The pipe has a 90° bend, and the pipe will require a supporting structure, called a thrust block, at the bend, as in Figure P9.700. We can use the ideas of momentum and impulse to understand why. Each second, 1000 kg of water moving at vz = 1.4 m/s changes direction to move at Vy = 1.4 m/s. a. What are the magnitude and direction of the change in momentum of the 1000 kg of water? b. What are the magnitude and direction of the necessary impulse? c. This impulse takes place over 1.0 s. What is the necessary force?

Question
70. ||| A water pipe in a building delivers 1000 liters (with mass 1000 kg) of water per
second. The water is moving through the pipe at 1.4 m/s. The pipe has a 90° bend, and the
pipe will require a supporting structure, called a thrust block, at the bend, as in Figure
P9.700. We can use the ideas of momentum and impulse to understand why. Each
second, 1000 kg of water moving at væ
= 1.4 m/s changes direction to move at
Vy = 1.4 m/s.
a. What are the magnitude and direction of the change in momentum of the 1000 kg
of water?
b. What are the magnitude and direction of the necessary impulse?
c. This impulse takes place over 1.0 s. What is the necessary force?
