A pushing force is applied to a 3.5-kg box. It starts from 2m/s and accelerates to 5.2 m/s covering the distance of 6 m. (a) Find the work done by the pushing force. (b) If friction is negligible, find the average force exerted on the box. Find (c) an impulse of the force, (d) the change in the momentum, (e) the final kinetic energy.

An applied force of 109 N is used to accelerate an object to the right across a frictional surface. The object encounters 19.4 N of friction. The object weighs 88.5 N. a) Calculate the normal force, (b) calculate the net force, (,c) calculate the coeficcient of friction (mu, µ), (d) calculate the mass (e) calculate the acceleration. please write neatly when explaining thank you
What average net force is needed to accelerate a 1380 kg car to a speed of 25 m/s in a time of 7 s? N
1) It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 60 mph? Suppose that μs=1.00 and μk=0.80. Express your answer to two significant figures and include the appropriate units. 2) A 22 cm diameter bowling ball has a terminal speed of 69 m/s. Suppose...
1) It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. Part A For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 70 mph? Suppose that ?s=1.00, ?k=0.80, and ?r=0.02. 2.) The forces in (Figure 1) are acting on a 1.0 kg object. What is ax, the x-component of the object's acceleration? 3.)A crate...
