3. m, V M Let's combine momentum and collisions with some of the other things we've learned. A small block of mass M 0.201 kg hangs on the end of a light, inextensible string, length R= 25 cm. A small dart (of mass m = 0.10 kg and small enough to be considered a particle) travelling in the horizontal direction collides with and remains fixed in the block. What is the minimum speed v of the dart such that the combined object completes a circular path around the support point of the block? (Hint: Consider the different parts of this question and analyse each separately before combining them. How fast must the block be travelling at the top? And don't forget significant figures.) Minimum speed = m.s
