Question
With friction turned on, set the initial velocity of the box to2.0 m/s, the coefficient of friction to 0.55, and the mass to 0.5kg. Assume the acceleration due to gravity has a magnitude of 9.8m/s2.
(a) What is the magnitude of the frictionalforce acting on the block while it is in motion?
(b) What is the acceleration of the box? Defineto the right as the positive direction, as in the simulation.
(c) What is the distance traveled by the boxbefore coming to rest?
(d) How much time passes before the block comesto rest?

Explanation / Answer
the initial velocity of the box u = 2.0 m/sthe coefficient of friction = 0.55 the mass m = 0.5 kg the acceleration due to gravity g = 9.8m/s2. (a) the magnitude of the frictionalforce acting on the block while it is in motion = mg
=2.695 N (b) the acceleration of the box a= -g
= -5.39 m / s ^ 2 i.e., it is in left (c) the distance traveled by the box beforecoming to rest is S = [ v ^ 2-u^2 ] / 2a
= 0.371 m (d) time passes before the block comesto rest t = ( v - u ) / a =0.371 s
