A rectangalar open box, 1m by 1m in plan and 2m deep, with a mass of 400 kg is launched into fresh water (9,810 N/m^3)
How deep will it sink?
If the the water is 2m deep what (more) mass is needed to cause the box to rest on the bottom?

A box with mass m is placed on top of a box with mass 2m as
shown in the figure. An external force F (t) = αt, where α is a
positive constant, acts on the bottom block and causes it to
accelerate from rest at t = 0. The two blocks have coefficient of
static friction μ between them, and the bottom box slides on a
frictionless surface. At what time will the top block begin to
slide relative...

A 10 kg box is pushed from rest by a truck for 2m. Once the truck stops pushing the box it is traveling 6 m/s.This box slides for 5 seconds before coming to a stop. If the specific heat is 2 joules per degree kg, how much did the temperature of the box change by and what is the average force applied by the truck?

differential equations: a mass of 2kg stretches a spring 1m. the mass is in a medium that exerts a viscous resistance of 8 newtons when the velocity of the mass is 2m/sec. the mass is stretched from its equilibrium position 1m and then set in motion with a downward velocity of (3sqrt(3) - 1) m/sec. Let g=10 m/sec^2 a)state and solve the initial value problem for u(t), the displacement of the mass from its equilibrium position b) what is the...

A box with a mass of 1.80 kg slides along a flat track with friction until it makes contact with a horiztonally mounted spring. At the instant that the box makes contact with the spring the box has a velocity magnitude of 2.00 m/s. The box slides and slows down until it comes to a rest after compressing the spring 11.0 centimeters. If the coeficient of kinetic friction between the track and box is 0.56, what is the spring constant...
