Question
(c) Is it possible to determine the coefficient of friction from these results in any simple manner? Explain your answer.
A small block of mass m = 185 g is released from rest at point (c) Is it possible to determine the coefficient of friction from these results in any simple manner? Explain your answer. (b) How much mechanical energy is transformed into internal energy as the block moves from point (a) What is its kinetic energy at point is 1.70 m/s. along the horizontal diameter on the inside of a hemispherical bowl of radius R = 30.8 cm, and the surface of the bowl is rough (see figure below). The block's speed atExplanation / Answer
a) KE(B) = 0.5*m*v^2
= 0.5*0.185*1.7^2
= 0.267 J
b) increase in internal enrgy = decrease in mechanical energy
= m*g*R - 0.5*m*v^2
= 0.185*9.8*0.308 - 0.267
= 0.291 J
c) No, beacuse here angle of inclination changes as the block slides down. so magnitude of frictional force also changes.
