A 15-kg block rests on a level, frictionless surface and is attached by a light string to a 10-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. 65 N
c. 59 N
b. 17 N
d. 37 N

Question 2

A 10-kg mass and a 6.0-kg mass are connected by a light string over a massless, frictionless pulley. If g = 9.8 m/s2, what is the acceleration of the system when released?
a. 2.5 m/s2
c. 7.8 m/s2
b. 6.5 m/s2
d. 9.8 m/s2
