Question

5. A block weighing 30 N is on a smooth horizontal surface and it is accelerated in the horizontal direction at the rate
of 4 m/s by a force. The net force acting on the block is (g= 10 m/s-)
1) 12 N
2) 120 N
3) 50 N
4) 10 N​

Answer 1

Answer:

12

Explanation:

Mass m=W/g =30N/10ms-1 = 3 kg

F= ma 3*4ms-1= 12N
