A 10 kg box with initial speed 7 m/s slides across the floor and comes to a stop after 1.8 s.
(a) What is the coefficient of kinetic friction?
μk =
(b) How far does the box move?
distance = m
(c) You put a 3 kg block in the box, so the total mass is now 13 kg, and you launch this heavier box with an initial speed of 7 m/s. How long does it take to stop?
Δt = s
