Two packing crates of masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley. The 5.00-kg crate lies on a horizontal table. The kinetic coefficient (?k) of friction between the table and the 5.00-kg crate is 0.25.
a. Draw a free-body diagram for each crate, using arrows to indicate all the forces acting on each crate.
b. Apply Newton’s 2nd law to find the acceleration of the 5.00-kg crate and the tension in the string.
Hint: friction force f = ?k x Normal Force (N)
