5. A 10.0 kg mass is tied to a 15.0 kg mass, and the string is draped over a massless, frictionless pulley. Determine the acceleration of the masses and the tension in the string.
5. A 10.0 kg mass is tied to a 15.0 kg mass, and the string is draped over a massless, frictionless pulley. Determine the acceleration of the masses and the tension in the string.
Solution
let the tension be T and the accelearation a is downward for 15Kg mass.So
for 15Kg mass mg-T=ma which gives
15g-T=15a.
for 10 kg mass
T-10g=10a
adding both
5g=25a
so a = 1.96 m/s^2
Substituning it is any one equation
T-10g=10*1.96 = 99.96 N
