A 2.4kg block sliding on a rough horizontal surface is attached to one end of a horizontal spring ( k=188/m) which has its other end fixed. The block passes through the equilibrium position with a speed of 2.76m/s and first comes to rest at a displacement of 0.23m from equilibrium. What is the coefficient of kinetic friction between the block and the horizontal surface?

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
