A rectangular waterproof air mattress is 2.0m long, 0.50mwide and 0.08m thick. It has a mass of 2.0kg and is supporting an additional mass of m, while floating in the water,
calculate the mass, m, assuming the density of water is 1000kg/m^3 and density of air is...
k. i got the answer, the max speed is 0.28m/s.
The next part of the question is, for what value of x does the speed equal one-half the maximum speed.
What i did was to solve for x with v = 1/2(max speed)
I got the answer wrong.
Can someone point out where i went wrong?
A 0.40kg object connected to a light spring with a force constant of 19.6N/m oscillates on a frictionless horizontal surface. If the spring is compressed 4.0 cm and released from rest, determine (a) the maximum speed of the object.
F = -kx
Water at the top of Niagara Falls has a temperature of 10.0degrees celsius. If it falls a distance of 50.0m and all of its potential energy goes into heating the water, calculate the temperature of the water at the bottom of the falls.
