The figure below shows two blocks connected to each other by a light cable that passes over a pulley with negligible friction. The block of mass m1 = 4.50 kg lies on a horizontal table with negligible friction, while the block of mass m2 = 11.2 kg hangs vertically.

(a) What is the magnitude of the acceleration of each block (in m/s2)? (Here, a1 is the acceleration of m1,and a2 is the acceleration of m2.)

a1 = m/s2

a2 = m/s2

(b) What is the tension in the cable (in N)?
