    Mechanics doubts Paper 4

    Q2 i) as component of resultant given ( magnitude is not given only horizontal companonet of resultant) so...... 8 + 8 cos @ = 9 solve it for @ @=82.8... ii) horizontal component= 8 + 8cos 82.8 vertical component = 8 sin 82.8 now solve it for thsi equation... horizontal...

    Mechanics doubts Paper 4

    K.E= 1/2 m (1.5^2 - 2.5^2) k.e= 2m..... ignore minus sign here as it is energy....but decceleration is occuring that why minus sign.... W.d = f into d.... 2m/4 = f 1/2 m= f f=ma 1/2m=ma a= 1/2... ma= mg sin alpha as it is smooth plane so no friction exist...

    MECHANICS HELP

    Equation for Q: F-T=ma F is supposed to be greater cuz Q going downwards..... F woud be equal to weight of Q.......so (0.3 INTO 10)- T = 0.3a equation for P....... As table is smooth so no fricyion force applied..... only tension in string.... T= 1.7a now solve it...

    MECHANICS HELP

    eg.. u r given the force with the angle with horizontal.. u can resolve it by consuidring it right angle triangle..... su[ppose force = f angle = @ vertical component..... Fsin@ horizontal component = F cos@
