    How Much Energy Is Released in a Three-Part Explosion?

    Hi everyone, I've been trying to do this question here but I'm stuck on the last part: A 23.0 kg body is moving with a speed of 25.0 m/s in the direction of the positive x-axis when, owing to an internal explosion, it breaks into three parts. One part, which has a mass of 5.50 kg, moves away...

    Integrating x and 1+X^6/L^6 from 0 to L: Seeking Help and Tips

    Perhaps I'm doing something wrong in the problem. Here is the problem and what we are suppose to do is take the integral of the numerator and denominator and get a ratio for L, where lambda = dm/dx and dm = lambda. Once i got what dm was i substituted appropriately into the equation for the...

    Integrating x and 1+X^6/L^6 from 0 to L: Seeking Help and Tips

    No, the L^6 is just under the x^6.

    Integrating x and 1+X^6/L^6 from 0 to L: Seeking Help and Tips

    Hi everyone, I need some help integrating the following. I have been trying to integrate it but can't seem to get the correct answer and what it is suppose to be. Any help would be greatly appreciated: integral(x (1+X^6/L^6) dx) going from 0 to L The second one is similar: integral(...

    Kinematics: Solving Problems with Displacement, Velocity, and Acceleration

    Ok so i plugged the numbers into the first kinematic problem to get the speed at 21 sec which was 500 m/s. After that i used the 3rd equation listed in the quote above to get how high it went and i got the wrong answer from what it is suppose to be. Anyone know what i am doing wrong?

    Kinematics: Solving Problems with Displacement, Velocity, and Acceleration

    Ok so apparently i am suppose to show work which i have done on the problems. I haven't done much work on them except draw the pictures etc... For the first problem i know I'm suppose to use the two main kinematics problems which are: v = v0 + at and x = x0+v0t+.5at^2 For the last problem i...

    Kinematics: Solving Problems with Displacement, Velocity, and Acceleration

    Hello everyone, I'm new to this forum. I am kinda having trouble with a physics problem. Could someone please help me out with 3 problems. Thanks. A rocket is fired vertically with an upward acceleration of 27 m/s2. After 21 s, the engine shuts off and the rocket continues as a free...
