### volume of solid (calc 2)?

Find the volume V of the solid whose base is the circle

x^2 + y^2 = 25

and whose cross sections perpendicular to the x-axis are triangles whose height and base are equal.

help appreciated

thanks

1 AnswerMathematics7 years ago### internet connection sharing problem?

I used to use my lap top as a connector to get online from my xbox via the PC connected to the wireless network at the house. This worked for years. Recently, it has stopped working. Now when I go under properties of my wireless network and check the allow others to connect to the internet to get internet access (which is what used to work), it tells me "An Error Occured while internet connection sharing was being enabled"

Bridging the local with wireless does not work either. Any suggestions on how to fix internet connection sharing?

1 AnswerMathematics8 years ago### mass connected to pulley system: find speed?

A string, attached to a spring on one end and a weight on the other, is wrapped around a pulley. The cylindrical pulley has a radius of 10 cm and a mass of 5 kg. The weight also has a mass of 5 kg. The spring has a spring constant of 500 kg/s2 and is initially unstretched. When the block is released, it travels 12 centimeters to the floor.

Find the speed of the weight just before it hits the floor.

3 AnswersPhysics8 years ago### mass slides and hits a ball connected to a string: find angle theta?

A block of mass M moving with speed Vo (initial velocity) along a frictionless surface smacks a ball of

mass m suspended from a string of length L. The ball rises until the

string makes an angle θ with the vertical. The block is not moving after the collision.

Find an expression for θ in terms of M, L, m, Vo, and any necessary constants.

Here is a picture of the problem. Really confused. Any help is appreciated.

1 AnswerPhysics8 years ago### find magnitude and direction of forces?

A 50 kg diver stands so that her center of mass is at the end of a 2.4 m long diving board. The diving board has a mass of 30 kg, which is uniformly distributed along its length. There are 2 supports for the diving board (labeled A and B) which are 60 cm apart. Support Bhas a roller so that it cannot exert any horizontal forces. Find the magnitude and direction of the forces exerted on the diving board by Support A and by Support B.

1 AnswerPhysics8 years ago### final velocity of split pieces of a particle?

In a physics experiment, a particle (initial velocity v0 shown) decays into two pieces. One of the pieces is detected, and its final velocity is shown. The other particle is not detected. The

dotted arrows labeled A - E show five possible directions for the

final velocity of the other piece. (Note: Vectors are not drawn to scale.) Which of the labeled directions (if any) are physically possible? (List all possibilities.) Explain how to distinguish those that are possible from those that are not.

1 AnswerPhysics8 years ago### speed after collision of 2 vehicles?

An 800 kg car going north with a speed of 20 m/s collides at an intersection with a 1000 kg car going east with a speed of 12 m/s.

Suppose the cars in the question 4 did not stick together during the collision, but it is known that the 800 kg car had a speed of 10 m/s and was moving in a direction 45° east of north immediately after the collision. Find the speed and direction of the 1000 kg car immediately after the collision.

1 AnswerMathematics8 years ago### find direction and magnitude of linear momentum?

A radioactive nucleus, initially at rest, decays by emitting an electron and a neutrino perpendicular to each other. The linear momentum of the electron is 1.2 x 10-22 kgm/s and that of the neutrino is 6.4 x 10–23 kgm/s. Find the direction and magnitude of the linear momentum of the nucleus as it recoils.
