a. 6.1E+3 N
b. 2.0E+4 N
c. 6.0E+4 N
d. 2.6E+4 N
e. 6.7E+3 N
Question 2
A 14-kg block rests on a level frictionless surface and is attached by a light string to a 5.0-kg hanging mass where the string passes over a massless frictionless pulley. If g = 9.8 m/s2, what is the tension in the connecting string?
a. 2.6 N
b. 21 N
c. 49 N
d. 36 N
e. 190 N
