Answer:
78°
Step-by-step explanation:
The angular distance of an arc is twice the angle that forms it if that angle lies of the edge of the circle.
By this, Arc AK has angular distance 158°.
Arc JL = 202°.
Arc KL = 122°.
By subtracting these we get 80° for Arc JK.
Arc KA = 158°.
Arc AJ = KA - JK
AJ = 158-80
AJ = 78°

Answer:
367.64 meters
Step-by-step explanation:
Using the kinetic equation where:
<em>Vf ^ 2 - Vi ^ 2 = 2ax
</em>
We know that:
<em>Vf = 0 m / s
</em>
<em>Vi = 50 m / s
</em>
<em>
</em>
The acceleration can be calculated by means of F = M.a
F = -8500 (because it is stopping, braking force) and m = 2500 kg
We have left that a = F / M = -8500/2500 = -3.4 m / s ^ 2
Now reorganizing we have that:
<em>x = -Vi ^ 2 / 2a
</em>
<em>
</em>
replacing the values is:
<em>x = - (50 ^ 2) / (2 * -3.4)</em> = 367.64 meters and this would be the distance the car travels when it stops.
