Hi!Question:Two packing crates of masses m1 = 10.0 kg and m2 = 6.50 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The 6.50 kg crate lies on a smooth incline of angle 45.0°. Find the acceleration of the 6.50 kg crate.
_________m/s2 (up the incline)
Find the tension in the string.
_________ N
Thank you so much

    I assume the m1 is hanging vertically. This is called an Atwood machine

    the force of gravity acts on both, on m1,it is vertical, m1*g
    On m2, it is downward,of course, but the component down the plane is m2*g*sinTheta

    Net force=totalmass*acceleration
    solve for a.
    The tension? at M1,
