Asked by jzee11
How mush force must be exerted at an angle of 45 to top of a table to push along a weight when the frictional resistance to be overcome is a force of 2kg.
Force is given in kg so i understand like this: N=kg.m/s^2 so the force in N is such when applied to 2kg mass gives unit acceleration. correct?
Ans- cos@=2/F ; @=45
F=2.8 kg.
