Answer:
5.74 m/s
Explanation:
The work-energy theorem says that the work done an object is equal to its change in kinetic energy. Work equals force times distance, and for a box on level ground, the friction force equals the weight times the coefficient of friction.
W = ΔKE
Fd = KE
mgμ d = ½ mv²
gμ d = ½ v²
(9.8) (0.165) (10.2) = ½ v²
v = 5.74 m/s
