SPH301 Dynamics
6. A string is tied to a 3.2 kg object on a table and a 1.5 kg object hanging over a pulley. The
coefficient of kinetic friction between the 3.2 kg object and the table is 0.30.
a. Calculate the acceleration of each object. (Ans: 1.1 m/s? [R], 1.1 m/s? [Down])
b. Determine the magnitude of the tension in the string. (Ans: 13 N)
c. How far will the objects move in 1.2 s if the initial velocity of the 3.2 kg object is 1.3 m/s
[right]? (Ans: 2.4 m)
3.2 kg
1.5 kg
