a force of 60N is applied on a object of 30 kg to move it with a constant speed of 6m/s .
The answer in my book is 60 n . I'm confused .does this mean that the force we will apply will be equal to the frictional force. ( if i will write 70 n then will the answer be same 70N???)
Does friction depends upon the velocity??
Please explain.
