is connected to a 2.4 kg mass. The pulley is
massless and frictionless, and the connecting

of 8 N, and thus has a downward acceleration
of only 4.8 m/s^2.
The acceleration of gravity is 9.8 m/s^2.

What is the tension in the connecting string? Answer in units of N.

What is the angle θ? Answer in units of ◦
