Consider this situation: A police officer arrives at the scene of an accident and finds a load of straw bales partly on the back of a pickup truck and partly on the hood of a Jaguar sedan. Both vehicles are facing in the same direction. The pickup is in front of the Jaguar. The truckdriver claims that she was stopped at the stop sign when the Jag drove into the back of her truck. The Jaguar driver claims that he was stopped behind the pickup when the truck suddenly backed up. Given this information decide whether each statement is true or false.True If the vehicles were both moving (truck in reverse and car forward), the pickup must have been moving faster.True The pickup could have backed into the Jaguar.False These results are impossible. The bales would have fallen forward in this type of accident.True Regardless of fault, the apparent motion of the bales results from them seeking the natural state of rest.True There is not enough information to determine who is at fault.False The Jaguar must have driven into the pickup.Your textbook is a useful resource for this question.

The block A with mass of 80 kg slides along the top of the block B with mass of 110 kg. The block A has an acceleration of 3.0 m/s2 when a horizontal force F of 700 N is applied, as in the Figure. There is no friction between the block B and a horizontal frictionless surface, but there is friction between the two blocks. Calculate the acceleration of the block A is going to B during the time that the block A remains in contact.
Mariana and Jun are both pushing on a box. Mariana pushes the box to the right and Jun pushes to the left. The box is on rollers and so is essentially frictionless with the floor, but Mariana and Jun do have friction with the floor. Jun is "winning" the pushing match and all three objects, Jun, the box, and Mariana are accelerating to the left. Consider the following forces: fm: the force of friction on Mariana f;: the force of friction on Jun FMB: the force of Mariana on the box FJB: the force of Jun on the box Which of the listed forces must be equal in magnitude and opposite in direction? Of; and FMB Mariana box Jun fm and FMB fm and fj no two of the four listed forces must be equal and opposite. FMB and FJB
It may appear at first glance that Newton's 2nd and 3rd laws are independent claims. This, however, is not true - Newton's 3rd law is simply a consequence of Newton's 2nd law. In this problem, you will prove Newton's 3rd law for the normal contact force between two objects, using only Newton's 2nd law. Consider two blocks with masses m₁ and m₂ in contact, with external forces F₁ and F2 applied, as shown in the figure. The free body diagram for each block is also given, with internal forces fa and f, as shown. F₁ F₁ fa fb ΣF = ΣF = m₁ m2 Submit F₂ Complete the equations of motion for the entire system, as well as blocks 1 and 2 individually. Note, the forces have a signed magnitude, where positive values correspond to the positive x-direction ΣF= = (m₁ + m₂) a = m₁ a = m₂ a Use the above equations to write fa in terms of only fr: fa = m₁ You have used 0 of 4 attempts m₂ F₂ Save Calculator
Your friend's 11.1 g tassel hangs on a string from his rear-view mirror. When he accelerates from a stoplight, the tassel deflects backwards toward the rear of the car. If the tassel hangs at an angle of 6.89° relative to the vertical, what is the acceleration of the car?
In a fit, a toddler throws straight down his favorite 1.5 kg toy with an initial velocity of 2 m/s. What is the magnitude of the change in velocity of the toy from t = 0.14 seconds to t = 0.31 seconds?
in Monkey and hunter case . my doctor want me to write a 5 lines about what I have learned from this screenshot. ( The simulation shows the classic physics situation of a monkey and hunter. In this case, the hunter is trying to tranquilize the monkey, so the monkey can be relocated to a better habitat. The monkey is clever—when the tranquilizer dart (in blue) leaves the gun, the monkey (in purple) lets go of the tree branch, and starts to fall straight down. Note that there is a net (not shown) at the bottom to catch the monkey, so the monkey won't get hurt.)
The soccer ball shown weighs I lb and has a velocity of 20 fps at 40° to the horizontal prior to striking the soccer player's head. After the soccer player heads the ball, it has a velocity of 30 fps at 20° to the horizontal. If the duration of the impact is 0.15 sec, determine a. Express the initial and final velocities of the ball in Cartesian vector form b. Magnitude and direction of the average force exerted on the soccer ball by the player's head in Cartesian vector form.
Dr. Miller is conducting an experiment. He has a stack of books on a table which is frictionless and flat. He applies a force F on the stack, and finds that it accelerates at 3.0 m/s². He then adds a book to the stack. This is a physics textbook that has a mass of 1.0 kg. He then applies the same force F on the stack and finds that now the stack accelerates at 2.0 m/s². What was the mass of the original stack of books? a) 1.0 kg Ob) 2.0 kg c) 3.0 kg O d) none of the above
Two people, one with a mass of 60 kg and one with a mass of 45 kg, sit on 5 kg frictionless carts that are initially at rest on a flat surface. The lighter person pushes on the more massive person, causing the latter to accelerate at a rate of 3.0 m/s2 toward the east. What are the magnitude and direction of the lighter person’s acceleration vector? The acceleration is_____ m/s2 toward the choose one ( East, West, North , south)

In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incredible speeds. 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.
Boxes A and B are in contact on a horizontal, frictionless surface. Box A has mass 20.0 kg and box B has mass 5.0 kg. A horizontal force of 100 N is exerted on box B. What is the magnitude of the force that box B exerts on box A?
