Can someone help me check my work on the other problems, and tell me if they are correct?

can someone please check my work?

What's nil ?

Ok, I redid the problem considering, like you said, the kinetic energy of both linear and rotational movement. so, (0.5)(9.81)(0.81) = (1/2)(0.5)(0.075^2)(w^2) + (1/2)(0.001125)w^2 ---> w=44.68 rad/sec. and velocity when the ball leaves the table is 5.147m/s and d = 2.75meters right?

ok, so b) w = 44.92 rad/sec c) Would the initial velocity of the ball when it leaves the table still be 3.987m/s?

1) Give the conditions for the equilibrium of an extended object. An extended object is at equilibrium when no force is acting on it. 2) A uniform ladder of length 6.0m and mass 12.0kg is placed against a smooth vertical wall. The ground is rough. a) Calculate the force on the ladder...

A solid sphere of diameter 0.15m and mass 0.5kg is released and rolls without slipping down the ramp. The ramp is 0.81m high and is on a table. The table has a height of 1.40 meters. The balls move freely once it leaves the table. a) What is the moment of inertia of the ball about the axis of...

cepheid, I followed what you did and still got -32/3 for #2, but the correct answer is -16/3

HELP:Volume generated("shell") Find the volume generated when the region bounded by the graph of f(x) = 4x^2 and the graph of H(x) = 4 is rotated around the line y = -1 How do I solve this? How do I know if, when rotated, if the solid form a "shell" or a disc, or a washer?

1) Find the area of the region bounded by the graphs of f(x) = x^2 - 5x + 3 and H(x) = -x Is H(x) an antiderivative? how do I solve this? 2) Find the area of the region bounded by the graphs of x - y^2 + 2y + 4 = 2 and 2y - 2 - x = 0 so, x = y^2 - 2y - 2 and x = 2y - 2 I...

from there I was suppose to compute as x is goes from 0 to 1 I got 0, but the answer is -1

how do I find to antiderivative of: x((2x^2) - 2)^3

Thanks Andrew Mason!

It does not give the temperature nor speed of sound.

Thanks spacetime! :smile:
