The force acting in the front direction is the 130N.
The frictional force is acting backwards 30N.
1) The net force is 130N - 30N = 100N
2) s = ut + (1/2)at^2 u = 0, Start from rest, s = 25m t =5.
25 = 0*5 + (1/2)* a * 5^2.
25 = 0 + 25/2 * a.
25 = (25/2)a. Divide 25 from both sides.
1 = (1/2)* a. Cross multiply.
2 = a.
a = 2 m/s^2.
3) Mass of the box
Net Force, F = ma
100 = m*2. Divide both sides by 2.
100/2 = m
50 = m.
m = 50 kg.
4) Final velocity , v = u + at.
v = 0 + 2*5 = 10 m/s.
Kinetic Energy, K = (1/2) * mv^2.
= 1/2 * 50 * 10 * 10.
= 2500 J.
Traditional media include the use of billboards, television and other forms of print media. Hence, <em>Dunkin</em><em>'</em><em> </em><em>Donuts</em><em> </em><em>billboard</em><em> </em>is a form of traditional media.

<u>Answer:</u>
After 3 hours Amanda catch up to Ben.
<u>Explanation:</u>
Speed of Ben = 4 mi/h
Speed of Amanda = 6 mi/h
Time after Amanda starts after Ben leaves = 1.5 hours.
Let the time taken for them to catch up be t hours.
Distance traveled by Ben in time (t+1.5) = 4*(t+1.5)
Distance traveled by Amanda in time t = 6*t
Equating both the distances
4*(t+1.5)= 6*t
2t = 6
t = 3 hours
So after 3 hours Amanda catch up to Ben.
