Bob pushes on a friction-less cart and the cart has an acceleration of 8 m/s?. With this Information, answer the following two questions: Pre-Lab Question #1: If Bill pushes twice as hard on an identical 2F cart, what will be the acceleration? Pre-Lab Question #2: If Joann pushes half as hard as Bob, on a cart with half the mass, what will be the acceleration?

Tom enlists the help of his friend John to move his car. They apply forces to the car as shown in the diagram. Here F, = 437 N and F, = 359 N and friction is negligible. In the diagram below, the mass of the car = 3500 kg, e, = -25° and e, = 12°. (Assume the car faces the positive x-axis before the forces are applied.) F, (a) Find the resultant force (in N) exerted on the car. magnitude N direction (counterclockwise from the +x-axis) (b) What is the acceleration (in m/s?) of the car? magnitude m/s² direction (counterclockwise from the +x-axis)
A car manufacturer is designing a new, lighter sports car. It has a mass of 1,000 kg. They ran 5 trials to see how a change in force could result in a change of acceleration. Examine the table below to answer the following questions.

A 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?

Ms. Estes is trying to assess which of her Physics students best comprehend the concepts of mass and weight. Which students offer the most accurate descriptions of mass and weight? Albert: Weight is a measurement of the force of gravity acting on an object.Catherine: Weight is a measurement of how many atoms are contained in an object.Evelyn: Weight is a measurement of how strong the Earth pushes upward on an objectBetty: Mass is a measurement of how much space an object takes up.Delilah: Mass is a measurement of how much matter an object has and of its inertia.Francis: Mass is a measurement that explains why all objects accelerate at -9.8 m/s2.
Two forces are applied to a 4.0 kg cart on a rough surface as shown. At a certain instant, force A is 32 N to the right, and force B is 20 N to the left. The friction force is 2.0 N. What is the acceleration of the cart at this instant, in m/s?? (Hint: What is the direction of the friction in this case? Draw a free-body diagram.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
