Blocks A (2.0kg) and B (3.0kg) are placed in contact on a horizontal surface that can be considered frictionless. A constant horizontal force of 10N is applied to block A, pushing it toward block B so that the blocks move together. What is the magnitude of the acceleration of the blocks?
a) 5.0m/s2
b) 2.0m/s2
c) 1.7m/s2
d) 1.0m/s2
