Question

The masses of 10 kg and 20 kg respectively are
connected by a massless spring. A force of 200
Facts on the 20 kg mass. At the instant shown
the 10 kg mass has an acceleration of 12 ms
what is the acceleration of 20 kg mass?

Answer 1

Answer:

Divide it by cos titha 30 degree by sin titha 90 it may come zero but you can further explain it okay

Answer 2

Explanation:

Kx = 10×12

     = 120 N

F net =m.a

200 -120 = 20.a

80= 20.a

a= 4 m/s²
