A block of mass M is pulled along a smooth horizontal floor by a force of magnitude F inclined at an angle q as shown in the figure below. The next two questions pertain to this situation. The symbol g has the value +9.8 m/s2.
Which of the following statements concerning N, the vertical force that the floor exerts on the block, is true?
N < Mg
N = Mg
N > Mg
If M = 1.5 kg, F = 6.0 N, and q = 45o, what is a, the magnitude of the acceleration of the block?
a = 2.0 m/s2
a = 2.8 m/s2
a = 4.0 m/s2
a = 5.7 m/s2
a = 6.9 m/s2
