Question

MISSING Mich) 20 cm 14 cm A hole is punched in a full milk carton, 14 cm from the bottom as shown (top is 20 cm high). What is the initial velocity of outflow? 1.08 m/s 1.66 m/s 3.43 m/s 5.24 m/s 17 m/s

Answer 1

Q.1

Distance of hole from the top = 20 cm - 14 cm = 6 cm = 0.06 m = h

velocity of outflow is given by

$v = \sqrt{2gh}=\sqrt{2(9.8)(0.06)}$

= 1.08 m/s

Q.2

let Tension in the cable is T.

for the equilibrium of the shark , the cable must balance the weight of the shark. Therefore,

T = 9000 N
