The acceleration a is correct.um to find acceleration cant you use a=gsinθ, but if you use that its 10xsin(5.740) which equaks 1.001 because if sinθ=10/100 then θ=5.74. However if I use your equation i get a=4.5m/s/s
In the problem they have askedhow do i calculate af?
This step is wrong.so is af = 4.500 - 1.001?, then the braking force is 1000*3.499=3499???????????????
mg*sinθ ......> Force acting on the sledge due to gravity in the downward directionwhats the difference between a and gsinθ?
