T = 3m2m1g/(m1+m2)
T = 3m2m1/(m1+4m2)
T = 3m2m1g/(m1+4m2)
T = m2m1g/(m1+m2)
Solution:
Step 1: Apply Newton's second law to the block and bucket. For the block: m1*g - T = m1*a For the bucket: T - m2*g = m2*a Step 2: Add the equations to eliminate T: m1*g - m2*g = (m1 + m2)*a Step 3: Solve for a: a = (m1 - m2)*g / (m1 + m2) Step 4: Substitute a back into one of the original equations to solve for T. Using the block equation: T = m1*(g - a) Step 5: Substitute a: T = m1*g - m1*(m1 - m2)*g / (m1 + m2) Step 6: Simplify T: T = m1*m2*g / (m1 + m2)
