A 3.00-kg block is connected to two ideal horizontal springs having force constants k1 = 25.0 N/cm and k2 = 20.0 N/cm (Fig. P7.62). The system is initially in equilibrium on a horizontal, frictionless surface. The block is now pushed 15.0 cm to the right and released from rest. (a) What is the maximum speed of the block? Where in the motion does the maximum speed occur? (b) What is the maxi-mum compression of spring 1?

Solution to 70P Step 1 Mass of the block =3kg Distance the spring was compressed =15cm=15x10 m 2 K =25N/cm =25x10 N/m 2 1 2 K220N/cm =20x10 N/m
