A badger is trying to cross the street. Its velocity vvv as a function of time ttt is given in the graph below where rightwards

is the positive velocity direction. A set of black coordinate axes are given with the vertical axis labeled "v (m/s)" and the horizontal axes labeled "t (s)". A curve that relates v to t is shown in blue. It begins with a straight line of endpoints (0,0) and (1,5). This first line is connected to a second line with endpoints (1,5) and (3,-5). This second line is then connected to a third line of endpoints (3,-5) and (6,-5).

The badgers displacement from its position at point <em>t </em>= 2, to its position at point <em>t </em>= 3 is 25 meters

<h3>Which method can be used to calculate the displacement of the badger?</h3>

The points on the graph are;

(0, 0), (1, 5), (3, -5), (6, -5)

The point <em>t </em>= 2 is between (1, 5) and (3, -5)

The slope, <em>m</em>, of the line containing the point <em>t </em>= 2 is therefore;

  • m = (-5 - 5)/(3 - 1) = -5

The equation of the line is therefore;

v - 5 = -5•(t - 1)

v = -5•t + 5 + 5 = -5•t + 10

v = -5•t + 10

At <em>t </em>= 2, we have;

v = -5×2 + 10 = 0

The velocity at <em>t </em>= 2 is 0 m/s

The value of the acceleration is the same as the slope, <em>m </em>= a = -5

Given that the initial velocity at <em>t </em>= 2 is 0, we have;

∆x = u•t + 0.5•a•t²

At <em>t </em>= 3, the time of travel from the time <em>t </em>= 2 is 1 seconds, which gives;

∆x = 0×5 + 0.5×(-5)×1² = -2.5

The distance traveled between points,<em> </em><em>t </em>= 2 and <em>t </em>= 3 is ∆x = -2.5, which is 2.5 meters in the direction opposite to the initial direction.

What is the magnitude of the average force required to stop an 1200 kg car in 9.0 s if the car is traveling at 80 km/h ? Express
Nutka1998 [239]

Answer: 2960N

Explanation:

According to newtons first law of motion, force = mass × acceleration

To get acceleration,

Acceleration = velocity/time

Velocity = 80km/hr

Converting the velocity to m/s

80×1000/1×3600

velocity = 22.2m/s

Time = 9secs

Acceleration=22.2/9

Acceleration = 2.47m/s²

The get the force

F= 1200×2.47

F = 2960N
