Suppose there is a kinetic friction force of 14 N acting on the 4 kg block as the system accelerates. What is the acceleration of the 4 kg block?
there is a picture and I was going to post the URL for it but I'm not allowed to post URLs so I'll try to describe it.
There's an atwood machine with the 4 kg block on the left hand side sitting on a surface while a 2 kg on the right is being held in air by a string.
A)0.9 m/s2
B)5 m/s2
C)1.5 m/s2
D)0 m/s2
E)3.3 m/s2
When I tried solving it, I got .93 m/s^2 for the system. Would the acceleration for the system be the same as the 4 kg block? Thank you.
