Question

A box is pulled with a horizontal 60 N tension force. There are 4 N of friction acting on the box. It accelerates at 1.2 m/s2. What is the mass of the box? *​

Answer 1

Answer:

46.67kg

Explanation:

friction always acts opposite of motion. consider it as negative force.

total force on the box is 56N.

Now we know f and we know a=1.2m/s^2

applying the formula F=ma

we get the answer.
