Please help me solve question

A massless and frictionless pulley hangs from the ceiling on a cable that can sustain the maximal tension Tmax: 350 N. A block of mass m is attached to a lightweight cord that passes overthe pulley. You pull the other end ofthe cord straight down applying the force F = 121 N, and the block moves with the upward acceleration ay= 1.2 m/s2. I Find the mass m of the block. (4 points) I Find the tension in the cable from which the pulley hangs. (3 points) I What is the maximal force Fmax you can apply before the cable breaks? (3 points) Your
