Answer:
10.32m/s
Step-by-step explanation:
F = ma
T -mg sinθ-f =ma
We can conclude that T = 300 newtons by taking a freebody of the cable. So we need to determine only the frictional force.
f(n) = 0
mgcosθ = N = 0
N = mgcosθ
T - mg sinθ - u mgcosθ = ma
a = T - mg (sinθ + u cosθ) / m

a = 5.32m/s^2
Use constant acceleration kinematics:
