Acceleration from Net force, ##a = \large \frac{73.06}{5}## = ##14.61 \;m/sec^{2}## to the right.
A force of 100N applied to a body which has 5kg mass. Coefficient of static friction(μs) is 0.60 and Coefficient of kinetic friction(μk) is 0.55.
A) ##μ_{s} = 0.60##; ##μ_{k} = 0.55##
##F_{s}^{max} = F_{n}*μ_{s}##
##F_{s}^{max} = 49*0.60 (F_{n} = 9.8 \;m/sec^{2} *(5kg) = 49N)##
##F_{s}^{max} = 29.4 N##
Net force, ##F_{net} = 100 – 29.4N = 70.6N##
Acceleration from Net force, ##a = \large \frac{70.6}{5}## = ##14.1 \; m/sec^{2}## to the right.
Frictional force = ##F_{n}*μ_{k}##
Frictional force = ##49*(0.55) = 26.95N##
Net Force, ##F_{net} = 100 – 26.95 = 73.05N##
Acceleration from Net force, ##a = \large \frac{73.06}{5}## = ##14.61 \; m/sec^{2}## to the right.
