Box A has a mass of 35.0kg and Box B has a mass of 20.0kg. What is the tension on Box A if the acceleration of the system is -2.67m/s2 clockwise? A. 250.N B. 686N C. 436N D. 392N
The tension on Box A if the acceleration of the system is provided clockwise is 686N.
What is tension?
The tension is the force of pulling in the linear objects.
Given is the system of two masses hung over a pulley with a string. Mass of block A, M(A) =35kg, M(B) = 20kg and the acceleration clockwise a =-2.67 m/s²
The tension in the string of each block = T =m(g-a)
Substitute the values, we get
T = 35 x (9.81-(-2.67)) +20(9.81 +2.67)
T =436.8 N + 249.6
T = 686.4 N
Thus, the tension in the the block A will be approximately 686N.
