Two blocks with masses \(M_1) and \(M_21) are connected by a massless string that passes over a massless pulley as shown. (M_1) has a mass of (2.25 \text { kg}\) and is on an incline of \{\theta)_1=41.5^circl) with coefficient of kinetic friction ({\mu)_1=0.2051). (M_2\) has a mass of \ (6.75 \text{ kg)) and is on an incline of ( {\theta)_2= 35.5^\circl) with coefficient of kinetic friction ({\mu)_2= 0.1051). The two-block system is in motion with the block of mass (M_2 \\) sliding down the ramp. Find the magnitude (a_2 11) of the acceleration of \(M_21) down the incline. \\(a_2=\\) W Mext (m)/text(s)^{2} \\) M₁ M₂ Figure is not to scale.
