) through a hose having an outlet radius of 1.20 cm. If the
difference in pressure is measured to be P1 − P2
= 1.20kP a and the radius of
the inlet tube to the meter is 2.40cm, find
(a) the speed of the gasoline as it leaves the hose and
(b) the fluid flow rate in cubic meters per second.
On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 5.00 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 42.5 m/s at an angle of 26 ° above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball?
