Two objects are connected by a string of length 4.8 m and negligible mass. The 10 kg block is placed on a smooth table top(3.6 m from end of table),and the 7kg block hangs over the edge of the table. The 7 kg block is then released from rest at a distance of 1.2 m above the ﬂoor at time t = 0.The acceleration of gravity is 9.8 m/s^2. The acceleration of the 7kg block is 4.04 m/s^2. The 7 kg block strikes the ﬂoor and doesnot bounce.How long dies ittakethe7kgblocktostrikethe ﬂoor? Answer in units of s.
