A block of mass m1 = 4.20 kg on a frictionless inclined plane of angle 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.40 kg hanging vertically. (a) What is the magnitude of the acceleration of each block? m/s2 m1 = m2 = m/s2 (b) What is the direction of the acceleration of m2? O m2 accelerates downwards O not enough information O m2 accelerates upwards (c) What is the magnitude of the tension in the cord?

Question
i never figured out how to solve problems like this and want to make sure i have the method down by the test
A block of mass m1 = 4.20 kg on a frictionless inclined plane of angle 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.40 kg hanging vertically.
(a) What is the magnitude of the acceleration of each block?
m1 =
m/s2
m2 =
m/s2
(b) What is the direction of the acceleration of m2?
O m2 accelerates downwards
O not enough information
O m2 accelerates upwards
(c) What is the magnitude of the tension in the cord?
