there are 2 part for this problem I got the part one but i didnt get another one so helpppp please...
1)A 44.4 kg box initially at rest is pushed 5.3m along a rough, horizontal floor with a constant applied horizonta force of 181.646N.
The acceleration of gravity is 9.8 m/s2.
If the coefficient of friction between box and floor is 0.38, find the work done by the friction. Answer in units of J.
The answer for this question is -876.33
2) find the final speed of the box. Answer UNits of m/s. Please help me in this problem...post the reply as soon as possible if u can...
