diameter 3.0 cm. The gauge pressure at
the left is 100 kPa.
(a) [6pt] Calculate the speed at which
water emerges from the pipe on the
right. The continuity equation implies that
right portions of the pipe. Then (b) [6pt] Calculate the pressure on the gauge at the right. According to the Bernoulli equation, with to two significant digits. so where 1 and 2 denote the left and 6 Problem 6: [12 pt] A block of mass
resting on a cart of mass
kg on a level air
track, on which the cart can slide with negligible
friction. The coefficient of static friction between the
block and the cart is
The cart is
accelerated by a force applied parallel to the air
track as shown. The block accelerates with the cart
(a) [6pt] Show and clearly label all forces acting on the two free body diagrams below, one for
the cart and mass together, and one the mass in isolation. If any of your notation is not
standard, be certain to define it. (b) [6pt] Find the maximum force
