025 (part 1 of 4) 10.0 points A man pushes a 24 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually in- creases his force so that the force he exerts on the box varies in time as F (7.7 N/s) t. Af- ter 4 s, he stops pushing the box. The force is always exerted in the same direction. What is the velocity of the box after...

A storeho use worker pushes a box with a refrigerator (mass:96.0-kg) at constant velocity for a distance of 11.0 m. He pushes in the direction parallel to the horizontal floor. A 250.0-N frictional force opposes the motion of the box. Use Newtons second law and definition of work to answer the questions below. (a) (1 point) What is the acceleration of the box? as (b) (2 points) What is the net force, acting on the box? Write down Newtons second...

A construction worker attempts to lift a uniform beam off the floor and raise it to a vertical position. The beam is 2.50 m long and weighs 600.0 N. At a certain instant the worker holds the beam momentarily at rest with one distance d = 1.50 m above the floor, as end at shown in the figure, by exerting a force P on the beam, perpendicular to the beam. (a) What is the magnitude P? (b) What is the...
