Walking without slipping requires a static friction force between your feet (or footwear) and the floor. The force on your foot as you push off the floor is forward while the force exerted by your foot on the floor is backward. But what about your other foot, the one moved during a stride? What is the direction of the force on that foot as it comes into contact with the floor? Explain.
When you are in a car's passenger seat (on the right –US car), and the driver turns left, you are thrown against the car door. Your little nephew says there is a force pushing you out of the car. Explain what is really happening, using good physics.
When an object falls freely under the influence of gravity there is a net force mg exerted on it by the Earth. Yet by Newton’s third law the object exerts an equal and opposite force on the Earth. Does the Earth move? Explain.

- The starship Enterprise has its tractor beam locked onto some valuable debris and is trying to pull it toward the ship. A Klingon battle cruiser and a Romulan warbird are also trying to recover the item by pulling the debris with their tractor beams as shown in Figure P5.25. a. Given the following magnitudes of the tractor beam forces, find the net force experienced by the debris: FEnt = 7.59 106 N, FRom = 2.53 106 N, and FKling = 8.97 105 N. b. If the debris has a mass of 2549 kg, what is the net acceleration of the debris? FIGURE P5.25arrow_forwardA block of ice (m = 15.0 kg) with an attached rope is at rest on a frictionless surface. You pull the block with a horizontal force of 95.0 N for 1.54 s. a. Determine the magnitude of each force acting on the block of ice while you are pulling. b. With what speed is the ice moving after you are finished pulling? Repeat Problem 71, but this time you pull on the block at an angle of 20.0.arrow_forwardAn aluminum block of mass m1 = 2.00 kg and a copper block of mass m2 = 6.00 kg are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in Figure P5.46, where = 30.0. (a) When they are released from rest, will they start to move? If they do, determine (b) their acceleration and (c) the tension in the string. If they do not move, determine (d) the sum of the magnitudes of the forces of friction acting on the blocks.

- A vertical cable supports two vehicles, a 1,207 kg convertible and a 1,461 kg truck, with the convertible directly above the truck. The cable is attached to a crane, which lifts the vehicles with an acceleration 1.05 m/s2. At one moment the convertible is moving at a speed of 3.40 m/s. Assume the cable does not stretch. (a) How do the velocity and acceleration of the two vehicles compare? 1. At any instant the truck has a lower velocity compared to that of the convertible and at all instants they have the same acceleration. 2. At any instant the truck has a higher velocity compared to that of the convertible and at all instants they have the same acceleration. 3. At any instant they have the same velocity and at all instants they have the same acceleration. (b) What is the tension, Tlower, (in N) in the cable between the convertible and the truck?

In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” He does this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Is the physics of this scene “Good,”“Bad,” or “Ugly?” Draw and Explain.arrow_forward
