An air bubble released by a submersible vehicle, 120 m below the surface of a lake,...
An air bubble released by a submersible vehicle, 120 m below the surface of a lake, has a volume of 1.55 cm3. The surface of the lake is at sea level, and the density of the lake water can be approximated as that of pure water. As the bubble rises to the surface, the temperature of the water and the number of air molecules in the bubble can each be approximated as constant. Find the volume (in cm3) of the...

An air bubble released by a deep-water diver, 120 m below the surface of a lake, has a volume of 1.65 cm3. The surface of the lake is at sea level, and the density of the lake water can be approximated as that of pure water. As the bubble rises to the surface, the temperature of the water and the number of air molecules in the bubble can each be approximated as constant. Find the volume (in cm) of the...

A ball is launched from a cliff that is 20.0 m above the surface of a very deep lake. SEE FIGURE. The initial speed is |v_1| = 40.0 m/s. The ball follows the one-dimensional trajectory schematically shown. Assume the magnitude of gravitational acceleration is g = 9.80 m/s^2. Neglect air resistance. The ball hits the water surface and moves downward toward the bottom of the lake with an UPWARD acceleration whose magnitude is |a| = 3.00 m/^2. (Scales shown in...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

A 2.5-liter object (mass: 2 kg) is released from rest at a depth of 20 m below the surface of the ocean. a) After it's released from rest, will the object rise to the surface or sink to the ocean floor? Explain. b) Determine the object's acceleration after it's released. c) Determine the speed of the object 3.5 seconds after it's released. d) How far has the object traveled in that 3.5 seconds?
A box with mass m = 1.2kg on an inclined frictionless surface is released from rest...
A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m. After reaching the bottom of the incline the box slides with friction (uk = 0.25) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a free body diagram for...
A small package is released from rest at A and moves along the skate wheel conveyor...
A small package is released from rest at A and moves along the skate wheel conveyor ABCD. The package has a uniform acceleration of 6.2 m/s2 as it moves down sections AB and CD, and its velocity is constant between B and C. The velocity of the package at D is 7.2 m/s. a) Determine the distance d between C and D. (Round the final answer to two decimal places.) in m. b) the time required for the package to...
(a) A 15.0 kg block is released from rest at point A in the figure below.
(a) A 15.0 kg block is released from rest at point A in the figure below. The track is frictionless except for the portion between points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,200 N / m, and compresses the spring 0.250 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface...
