Question
1.Two masses are connected together by a string and suspended by a second string
a) What force, F, must be applied to the upper string if the system falls at a constant velocity? Explain clearly.
b) What is the tension in the string connecting the two masses?
Two masses are connected together by a string and suspended by a second string What force, F, must be applied to the upper string if the system falls at a constant velocity? Explain clearly. What is the tension in the string connecting the two masses?Explanation / Answer
a)
force equation in vertical direction , F(required)-m1g-m2g=0 [as both are moving with constant velocity]
=>F(req)=15*9.8=147 N
b) for the lower body, in the vertical direction
T-mg =m*0
=>T-10*9.8=0
=>T=98N
