Question 1

At an instant when a 4.0-kg object has an acceleration equal to m/s2, one of the two forces acting on the object is known to be N. Determine the magnitude of the other force acting on the object.

2.0 N

13 N

18 N

1.7 N

20 N


Question 2

Exhibit 5-1
A 2.30 kg mass is suspended from the ceiling and a 1.70 kg mass is suspended from the 2.30 kg mass, as shown. The tensions in the strings are labeled and .




Use this exhibit to answer the following question(s).


Refer to Exhibit 5-1. A hand exerts an upward force of 6.70 N on the 1.70 kg mass. The magnitudes of the tensions are

T1 = 15.8 N; T2 = 10.0 N.

T1 = 15.8 N; T2 = 16.7 N.

T1 = 22.5 N; T2 = 10.0 N.

T1 = 22.5 N; T2 = 16.7 N.

T1 = 32.5 N; T2 = 10.0 N.
