Question 22

A high-precision calibration glider of mass 0.4 kg is being manipulated on a horizontal low-friction air-table. Two magnetic actuators exert forces F1\mathbf{F}_1F1​ and F2\mathbf{F}_2F2​ on the glider, where:

F1=[2a1.8] N and F2=[−3b] N \mathbf{F}_1 = \begin{bmatrix} 2a \\ 1.8 \end{bmatrix} \text{ N and } \mathbf{F}_2 = \begin{bmatrix} -3 \\ b \end{bmatrix} \text{ N} F1​=[2a1.8​] N and F2​=[−3b​] N

and a,b a, b\,a,b are constants. The glider's resulting acceleration vector is given by a=[5b10a] m s−2\mathbf{a} = \begin{bmatrix} 5b \\ 10a \end{bmatrix} \text{ m s}^{-2}a=[5b10a​] m s−2.

Determine the value of a a\,a and the value of bbb.
