Is this problem possible?

two people toss a raw egg in the egg toss. the force required to break the shell is 5N. the mass of the egg is 50g. estimate the maximum separation distance for the egg throwers. make whatever reasonable assumptions you need to about the launch angle and hand movement.

isnt an initial velocity needed for this problem?

Estimate!

That's what you've got to figure out. How fast can you toss that egg without breaking it?

Suppose the tossers are very, very, very strong. Then what?

Hint: How strong do they have to be to exert 5 N?

okay, so i figured the acceleration for the egg to break to be 100 m/s^2.
im estimating the max distance to be 100 m.
im stuck. how do i figure in the 100 m/s^2? the acceleration in both directions is gonna be constant. 0 in the x direction and 9.8 in the y direction.
so if the tossers are very strong, they would throw the egg very hard. leaving a high initial velocity. but that doesnt help with how to get the acceleration so high.

oooohhh, use centripetal acceleration to get initial velocity?

The max distance is what you're supposed to be figuring out. Don't guess at that answer!

You figured out the max acceleration the egg can withstand. Now use Bystander's hint!

using centripetal acc. i found the velocity to be 31.6 m/s with a radius(arm length) of .5 m. im assuming the launch angle to be 60 deg from the horizontal.
i have a feeling im way off though.
am i getting close?

Tom, are you still around. I looked at it like Work = mV^2 where V is the horizontal velocity. I don't know if I am right.
