A large block is held at rest on a frictionless surface and attached by a string to a small block that hangs in the air, as shown in the picture. The large block is released and slides on the surface a
distance of 2.24 meters in 1.74 seconds. The mass of the small block is 50.0 grams. Find the mass
of the large block.
