Explanation / Answer

here,

m1 = 3.3 kg

m2 = 2.4 kg

a)

the magnitude of accelration of masses, a = net force/effective mass

a = ( m2 * g - m1 * g * sin(theta)) /( m1 + m2)

a = ( 2.4 * 9.8 - 3.3 * 9.8 * sin(37)) /( 2.4 + 3.3)

a = 0.71 m/s^2

the magnitude of accelration is 0.71 m/s^2

b)

direction of masses is m1 up and m2 down

c)

let the tension in the string be t

for m2

m2 * g - t = m2 * a

t = 2.4 * ( 9.8 + 0.71)

t = 25.2 N
