Two objects are connected by a light string that passes over a frictionless pulley as shown in the figure below. Assume the incline is frictionless and take m1 = 2.00 kg, m2 = 7.35 kg, and θ = 50.0°.

1) Find the magnitude of the accelerations of the objects. (m/s^2)
2)Find the tension in the string. (N)
3)Find the speed of each object 2.50 s after being released from rest. (m/s)

ghazi · Answer

m2*g*sin theta-tension= m2* acceleration ...............(i)
tension -m1*g= m1*a ..................................(ii) by the help of equation one and two you can find acceleration

ghazi · Answer

$$m2*g*\sin \theta- T= m2*a$$
$$T-m1*g=m1*a$$

ghazi · Answer

add both the equations you'll get acceleration and after that substitute the value of 'a' to find out tension ......and to find the speed use v= (g-a)*t
