Two blocks, M1 and M2, are connected by a massless string that passes over a massless pulley. M1 has a mass of 2.25 kg and is on an incline of angle θ1 = 45.5∘ that has a coefficient of kinetic friction μ1 = 0.205. M2 has a mass of 6.25 kg and is on an incline of angle θ2 = 35.5∘ that has a coefficient of kinetic friction μ2 = 0.105. The figure illustrates the configuration. The two-block system is in motion, with block M2 sliding down the ramp. Find the magnitude a2 of the acceleration of block M2. a2 = m/s2

Two blocks,

M_{1}

and

M_{2}

, are connected by a massless string that passes over a massless pulley.

M_{1}

has a mass of 2.25 kg and is on an incline of angle

θ_{1} = {45.5}^{\circ}

that has a coefficient of kinetic friction

μ_{1} = 0.205 . M_{2}

has a mass of 6.25 kg and is on an incline of angle

θ_{2} = {35.5}^{\circ}

that has a coefficient of kinetic friction

μ_{2} = 0.105

. The figure illustrates the configuration.

The two-block system is in motion, with block

M_{2}

sliding down the ramp.

Find the magnitude

a_{2}

of the acceleration of block

M_{2}

.

a_{2} = ◻ m / s^{2}
