A cart of mass mA = 7.3 kg is pushed forward by a horizontal force F. A block of mass mB = 0.54 kg is in turn pushed forward by the cart.
If the cart and the block accelerate forward fast enough, the friction force between the block and the cart would keep the block suspended above the floor without falling down. Given g = 9.8 m/s2 and the static friction coefficient μs = 0.8 between the block and the cart; the floor is horizontal and there is no friction between the cart and the floor.
Calculate the minimal force F on the cart that would keep the block from falling down.
Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.
A mover has to move a heavy sofa of mass 158 kg to the second floor of the
house. He uses a rope to pull the sofa up a ramp from the first to the second
floor. As he pulls the sofa he makes sure that the rope is parallel to the surface
of the ramp which is at 30.0° to the horizontal. If friction between the sofa and
the ramp is negligible, and the sofa has an acceleration of 0.800 m/s², find the
tension in the rope (in N).

- If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.arrow_forwardYou push an object, initially at rest, across a frictionless floor with a constant force for a time interval t, resulting in a final speed of v for the object.
