A force F is given by F=at + bt2 , where t is time. What are the dimensions of a and b
Force = mass×accelaration = MLT−2
Dimension of ais same as that of Ft .i.e. MLT−3
Dimension of b is same as that of Ft2.i.e MLT−4
The dimensions of k in the equation F = - k x (where F is force and x is displacement)
