Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in Figure 4.29 to pull it out. (a) What force would you have to exert perpendicular to the center of the rope to produce a force of 12,000 N on the car if the angle is 2.00o?
In this part, explicitly show how you follow the steps in the Problem-Solving Strategy for Newton's laws of motion. (b) Real ropes stretch under such forces. What force would be exerted on the car if the angle increases to 7.00o and you still apply the force found in part (a) to its center?
A 1.0 kohm resistor is connected in series with a 10 mH inductor, a 30 V battery, and an open switch. at time t=0, the switch is suddenly closed. What are the voltage drops Vr and Vl 20.00 us after the switch is closed.
Two 1.50 V batteries -- with their positive terminals in the same direction -- are inserted in series into the barrel of aflashlight. One battery has an internal resistance of 0.240 Ω, the other an internal resistance of0.110 Ω. When the switch is..
A block with mass m = 15kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4234N/m after being compressed the distance x1 = 0.536m from the spring's unstretched length. The floor is frictionless except for a roug..
