In the system shown in Figure P5.23, a horizontal force F → acts on an object of mass m 2 = 8.00 kg. The horizontal surface is frictionless. Consider the acceleration of the sliding object as a function of F r . (a) For what values of F r does the object of mass m 1 = 2.00 kg accelerate upward? (b) For what values of F r is the tension in the cord zero? (c) Plot the acceleration of the m 2 object versus F 1 . Include values of F r from −100 N to +100 N. Figure P5.23

Solution Summary: The author explains how the object of mass m_1=2.0kg accelerates upward with a horizontal force.
In the system shown in Figure P5.23, a horizontal force
F
→
acts on an object of mass m2 = 8.00 kg. The horizontal surface is frictionless. Consider the acceleration of the sliding object as a function of Fr. (a) For what values of Fr does the object of mass m1 = 2.00 kg accelerate upward? (b) For what values of Fr is the tension in the cord zero? (c) Plot the acceleration of the m2 object versus F1. Include values of Fr from −100 N to +100 N.
A car driving at 27m/s veers to the left to avoid a deer in the road. The maneuver takes 2.0s and the direction of travel is altered by 20 degrees. What is the average acceleration during the constant speed maneuver? Do this in accordance with the example in the chapter.
