using F=MA, Mg=Mgsin in Relation we have;- M=20kg, F=40N, a=? :-(a) as subject formula, :- a=f/m, 40/20=2 mgsin= 2*10sin, 20sin30degree 10.

Total mass:-121kg Acceleration:-1.20 Force:-? :-Using formula we have F=MA F=121*1.20=145.2Ans to check:-F=MA :-making a subject of formula A=F/M 145.2/121=1.20 :-The total mass 121kg with acceleration 1.20 will need a force of 145.2

Total mass:-121kg Acceleration:-1.20 Force:-? :-Using formula F=MA whe have:-121*1.20=145.2Ans to Check:-F=MA making A subject formula we have:- A=F/M which gives us 145.2/121=1.20 :-The Total mass 121kg with the acceleration 1.20 will need a total force...
