What is the centripetal force of a jet making a turn with a radius of .75 km at a speed of 343 m/s

I know there's a conversion, and I know it's v^2/r but I keep getting 156 which isn't right.

Check your units. You need a mass.
 a = v²/r 
F = mv²/r

@peachpi I'm still confused. Sorry.

anonymous · Answer

I think the question is missing a piece of information. You need the mass to find the force.

I messed up sorry!

It's centripetal acceleration! @peachpi

anonymous · Answer

what units is your answer supposed to be in? I got 157 m/s², so I did the same thing you did.

anonymous · Answer

That's what I got- does this work as well:
1.6 x 10^2 m/s^2?

anonymous · Answer

yes that's the same thing to 2 sig figs

@peachpi can I post another question and have your help?
