4. [3/7 Points] DETAILS PREVIOUS ANSWERS MY NOTES A 7 kg box with initial speed 6 m/s slides across the floor and comes to a stop after 1.4 s. (a) What is the coefficient of kinetic friction? uk=_ (b) How far does the box move? distance = 4.5 X m (c) You put a 3 kg block in the box, so the total mass is now 10 kg, and you launch this heavier box with an initial speed of 6 m/s. How lon- does it take to stop? m = x s Additional Materials IJ eBook Submit Answer 5. [-12 Points] DETAILS MY NOTES A 25 kg box is being pushed across the floor by a constant force N. The coefficient of kinetic friction for the table and box is 0.19. At t = 7.0 s the box is at location m, traveling with velocity m/s. What is its position and velocity at t = 8.5 s? velocity: 3 = m/s _. position: I' = m
