Part A: The acceleration in the considered direction is positive. It means that the system will move on the left side.
Part B: The acceleration of the system is 0.65 m/s2.
Part C: The tension on the string is 424.5 N.
What is acceleration?
Acceleration is defined as the rate at which velocity changes with time, in terms of both speed and direction.
Given that two blocks connected by a cord passing over a small, frictionless pulley rest on the frictionless plane as shown in the figure.
Let's consider that tension on the string is T and the acceleration of the system is a that will be in the left direction.
The net force on the left block is given as,
\(100 g sin 30^\circ - T = 100 \times a\)
\(50g - T = 100 a\)
\(50g - 100 a = T\)
The net force on the right block is given as,
\(T - 50 g sin 53.1^\circ = 50 \times a\)
\(T - 40g = 50 a\)
\(T = 50 a + 40g\)
When equating both the values of T, we get a,
\(50g - 100 a = 50a + 40g\)
\(150 a= 10g\)
\(a = \dfrac { 10\times 9.8}{150}\)
\(a = 0.65\;\rm m/s^2\)
Part A: The acceleration in the considered direction is positive. It means that the system will move on the left side.
Part B: The acceleration of the system is 0.65 m/s2.
Part C: The tension on the cord is given as,
\(T = 50 a + 40 g\)
\(T = 50 \times 0.65 + 40 \times 9.8\)
\(T = 424.5 \;\rm N\)
Hence the tension on the string is 424.5 N.
