A 91 kg janitor wearing running shoes is running across an ice rink at a
speed of 3.2 m/s. They try to stop abruptly, but keep sliding across the
surface of the ice. The ice exerts a frictional force of 13.4 N to slow them
down. How far do they travel before halting to a stop?
Mary applies a force of 71 N to push a box with an acceleration of 0.45 m/s2. When she increases the pushing force to 79 N, the box's acceleration changes to 0.63 m/s2. There is a constant friction force present between the floor and the box.
(a)What is the mass of the box in kilograms?
?kg
(b)What is the coefficient of kinetic friction between the floor and the box?
Mary applies a force of 70 N to push a box with an acceleration of 0.60 m/s2. When she increases the pushing force to 82 N, the box's acceleration changes to 0.80 m/s2. There is a constant friction force present between the floor and the box. The mass of the box in kilograms is 60.

- You 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. You then repeat the experiment, but with a force that is twice as large. What time interval is now required to reach the same final speed v? (a) 4 t (b) 2 t (c) t (d) t/2 (e) t/4arrow_forwardFor t 0, an object of mass m experiences no force and moves in the positive x direction with a constant speed vi. Beginning at t = 0, when the object passes position x = 0, it experiences a net resistive force proportional to the square of its speed: Fnet=mkv2i, where k is a constant. The speed of the object after t = 0 is given by v = vi/(1 + kvit). (a) Find the position x of the object as a function of time. (b) Find the objects velocity as a function of position.arrow_forwardA black widow spider hangs motionless from a web that extends vertically from the ceiling above.
