Two particles A and B of mass 4 Kg & 3 Kg respectively are connected by a light in-extensible string which passes over a smooth fixed pulley. The particles are released from rest with the string taught.
a) Find the tension in the string
When A has traveled a distance of 2 m it strikes the ground & immediately comes to rest.
b) Assuming that B doesn't hit the pulley find the greatest height that B reaches above its initial position.

It's a mechanics questions and I've tried a lot but couldn't solve it. Somebody help me.😟😟

For part (a):

- make two F = ma equations, onne for each particle.
- each equation should include the tension in the string and the acceleration of the particles.
- treat them as simultaneous equations, eliminate the acceration and you should be able to find the tension.

Thanks, but it was b) that I really needed.(Original post by Pangol)For part (a):

Would have helped to have said that...

You need to use a two-stage suvat approach. Do one suvat for the period from rest up to the point where A hits the ground, and another from that point until B reaches its highest point.
