A 7.1 kg mass on a frictionless inclined surface
is connected to a 2.4 kg mass. The pulley is
massless and frictionless, and the connecting
string is massless and does not stretch. The
2.4 kg mass is acted upon by an upward force
of 8 N, and thus has a downward acceleration
of only 4.8 m/s^2.
The acceleration of gravity is 9.8 m/s^2.

What is the tension in the connecting string? Answer in units of N.

What is the angle θ? Answer in units of ◦

Step 1

Assuming to θ be the angle of the incline, for the 7.1 kg mass, the equation of motion is,

Step 2

For the 2.4 kg mass, the equation of motion is,

Step 3

From step 2, the t...
