Answer 1

Answer:

here is your answer acceleration is 1m/s^2

Explanation:

Downward acting on 2kg mass is 2g

downward acting force on 3kg mass is 3g

Taking component of 3g force

3gcosθ along normal

3gsinθ along inclination

normal and 3gcosθ cancel each other

Net force = 2g - 3gsinθ

= 2×10 - 3×10×sin30°

= 20-15

= 5 N

Total mass of the system = 3kg+2kg=5kg

$acceleration = \frac{net \: force}{total \: mass}$

$acc = \frac{5}{5}$

$acc = 1m {s}^{ - 2}$
