My -16.66 points UCFCalcPhysMechL1 6.0.001 A small block of mass m = 183 g is released from rest at point along the horizontal diameter on the inside of a hemispherical bowl of radius R 31.0 cm, and the surface of the bowl is rough (see figure below). The block's speed at is 1.81 m/s. 2R/3 (a) What is its kinetic energy at point (b) How much mechanical energy is transformed into internal energy as the block moves from point to point This electronic presentation to be used with SERWAN/JEW ETT.

Explanation / Answer

KE at point B = 1/2 (183 x 10^-3) (1.81)^2= 0.299 J

b) Energy converted to internal energy = 183x 10^-3 x 9.8 (0.31) - 0.299 J= 0.25 J apprx
