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°. http://www.webassign.net/serpse8/5-p-030.gif 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)

a)|dw:1329462014201:dw| \[m _{2}gsin \theta-T=m _{2}a\]&\[T-m _{1}g=m _{1}a\] so if you discard "T" from 2 equation yields a

b)now that find a you can find T from above for simplicity use from 2nd equation

when you find "a" put that in to :\[V=at+V _{0}\] here V0 is zero
