Question

Two blocks of mass 10 kg and 20 kg are connected by a light string . if two force of 80N and 20N are exerted on the system , the net acceleration of 10 kg will be ON HORIZONTAL FRICTIONLESS SURFACE . 1. 1 m/s2 2.2 m/s2 3. 0.5 m/s2 4.3 m/s2

Answer 1

Explanation:

m

=?

For mass m

1

; F=m

1

a

1

=10×12=120N

For mass m

2

;

200−F=20a

2

200−120=20a
