Now, would it be possible to solve this problem if they did not give the mass of the 3rd component (flying piece), if so, how? Thanks.

Homework Statement During testing of a fireworks device an engineer records that data shown in the table below when the device, initially at rest, explodes under controlled conditions into three components that spread out horizontally. Determine the unknown quantity...

You cannot say that Fnet = 0 because you are trying to find the acceleration while he's sliding down the hill. When he's stopped you know the net force is 0, but he is also not accelerating, so you simply cannot do this. Below is what your given and what is required for the question... Mu...

The attachment is unaccessible by me... It says pending approval.

Ok, that's what I thought... Thanks.

What's n? I think we use different symbols where I take this course...

If you could post the diagram that would help a lot so we would know where to start...

That's essentially what I did, but I thought that the net force was Fn - Fg... How come it is Fn + Fg? Attached is what I thought the FBD should look like.

Homework Statement An 82 kg pilot flying a stunt airplane pulls out of a dive at a constant speed of 540 km/h. a) What is the minimum radius of the plane's circular path if the pilot's acceleration at the lowest point is not to exceed 7.0g. Homework Equations Fg = mg Fnet = mv^2/r Fnet = ma...

For a: If you know the time in which the ball is in the air for you can easily find the horizontal range. You do this because you know the initial velocity, which is 18.5 m/s [18 deg above the horizontal]. You can calculate the horizontal speed, which is always constant in this case. Then...

Ok, so what you have to do is use the equations: Eg=mgh and Ek=1/2mv^2 You know that when the sled starts at the top of the hill there is no kinetic energy acting on the sled and at the bottom there is no gravitational potential energy acting on the sled. Since there is no friction, every...

Homework Statement A spaceship is accelerating upwards with an acceleration of 0.50g. It's mass is 2.0 x 10⁶ kg. What is the upward force this object is exerting? Homework Equations Fnet = ma Fnet = Sum of all forces. The Attempt at a Solution A = 4.9 m/s² [up] g = 9.8 m/s² [down] m =...

This was for my Grade 11 Physics class. Thanks for your guys' comments. They are really appreciated.

Hello, Here is a Physics Project I recently did on Tsunamis. Let me know what you think: http://www.vimeo.com/2878780 Thanks.

Thanks, I guess I was doing it right, I just forgot to convert the distance into meters.
