Questions
A horizontal force of 100 N is applied a block of mass 10 kg is placed on a rough horizontal surface with a coefficient of kinetic friction, . Find the acceleration of the block.
detailed solution
Correct option is B
Here, m = 10 kg, g = 10ms−2, μ = 0.5, F = 100 NForce of friction,f=μN=μmg=0.5×10kg×10ms−2=50NForce that produces accelerationF′=F−f=100N−50N=50Na=F′m=50N10kg=5ms−2Talk to our academic expert!
