Two objects are connected by a light string that passes over a frictionless pulley. The incline is frictionless, m1 = 2.00 kg, m2 = 4.00 kg, and θ = 52.0°.
a) Find the accelerations of the objects.
Magnitude
Answer in m/s^2
b) Find the tension in the string.
Answer in N
c) Find the speed of each object 3.00 s after being released from rest.
Answer in m/s

draw the free body diagram for both objects
and equate their motion using F=ma
you should get 2 equation with T and a as unknown
(T is the tension in the string which is same for both objects and a is the acceleration)
to solve for part a, eliminate the unknown T by substitution
to solve for part b, sub the value of T into either of the equation
to solve for part c, use kinematics equation since you already know a
