The power developed by the gun is given by formula - Power = Work done / time Power = n × (1/2 mv^2) / t Power = n/t × 1/2 × mv^2 Power = 1 × 1/2 × 0.05 × 700^2 Power = 12250 watt

ANSWER

Two blocks of masses 10g and 30g are fastened to the ends of a cord which passes over a frictionless pulley. The 10g block rests on the table, what min force must be applied to the 10g block to keep it on the table? What will be the tention in the cord under this condition? What will be the acceleration of the system and the tension in the cord when the force is withdraw?

V Sridhar 7 years, 7 months ago

For two blocks of masses fastened to the ends of a cord which passes over a frictionless pulley we have as per Newton's Second law :
motion for 30g or 0.03 kg mass will be , 0.03 g - T = 0.03 a ---------(1)
motion for 10g or 0.01 kg mass will be , T - 0.01 g = 0.01 a ---------(2)

Now the answer for the third part of the question can be obtained by solving (1) & (2) and putting g = 9.8 m/s^2

a = 4.9 m/s^2 and T = 0.147 N

for the first and second part of the question the eqn (2) has to be modified as under to accommodate minimum force, t, say to be applied . 't' will be applied downward to keep the 0.01kg mass from rising up
Also now the system will be at rest and so a = 0

The eqns will be now as under :

0.03 g - T = 0.03 x0 = 0 ----------------(3)
T - 0.01 g - t = 0.01x0 = 0 --------------(4)

solving (3) & (4) we get ,

t = min force to be applied = 0.196 N
T = tension = 0.294 N
