An empty tin can with height of 30cm and a diameter of 15cm is
open at one end and closed at the other end. If the vertical can,
with open end down, be slowly immersed in water, how far the water
will rise inside the can when the closed end is 10 cm below the
water surface?

An empty tin can with height of 30cm and a diameter of 15cm is
open at one end and closed at the other end. If the vertical can,
with open end down, be slowly immersed in water, how far the water
will rise inside the can when the closed end is 10 cm below the
water surface?
I know this is easy, but when I'm solving for h, I'm
getting a negative value, means that the can will be filled...

The rear window in a car is approximately a rectangle, 2.4 m
wide and 0.65 m high. The inside rearview mirror is 0.40 m from the
driver's eyes, and 2.10 m from the rear window. What is the minimum
length for the rearview mirror if the driver is to be able to see
the entire width and height of the rear window in the mirror
without moving her head? What is the minimum height for the
rearview mirror if the...

A 1600 kg sedan goes through a wide intersection traveling
from north to south when it is hit by a 2000 kg SUV traveling from
east to west. The two cars become enmeshed due to the impact and
slide as one thereafter. On-the-scene measurements show that the
coefficient of kinetic friction between the tires of these cars and
the pavement is 0.750, and the cars slide to a halt at a point 5.30
m west and 6.31 m south of...

Consider a 1.5m long 30cm wide flat plate exposed to two laminar
flows of air (6 m/s free stream top surface and 12m/s free stream
bottom surface) at 25ºC and atmospheric pressure. The top and
bottom surfaces of the plate are electrically heated (1.5 kW total
power, heaters assumed infinitesimally thin). The plate consists of
3 layers: a top and bottom layer of 1.0 cm balsa wood (k = 0.055
W/(m·K)), and a middle layer of 2.0 cm plywood (k...

A window of a car is found to be covered with 0.9cm of ice. If
the area of the window is 1 m2, and the ice is at -12 degrees
Celsius, what is the minimum heat required to melt all the ice?
Take the density of ice to be 900 kg/m3, the specific heat capacity
of ice to be 0.5 cal/g*K, and the latent heat of fusion to be 80
cal/g. Answer in kcal.
