A truck tows a car of mass 1000kg along a road, it accelerates at 0.5m/s². What's the tension of the tow line?
If the towline breaks when the car reaches a speed of 36km/h, how far will the car travel before coming to rest if a braking force of 5000 N is applied?
that is truthfully confusing -- why became the legally parked vehicle with a resident decal towed? Did the valuables supervisor have them tow your vehicle? i think the question is why did they tow the motor vehicle? i don't have self belief that that is considered robbery. you could in all probability be entitled to the fee from the tow employer lower back -- yet whilst there have been no different damages then i'm no longer too confident what you're searching for? If the supervisor had them tow it then your concern is with the supervisor and not the tow employer. in the event that they merely towed it then i might inquire approximately getting the charges lower back (in case you paid any)

Recall that tension is just a kind of force, and, from Newton's 2nd law of motion,
Force = mass * acceleration
So
Tension = 1000 * 0.5 = 500 N
******************************************************************************************************************
The braking force is 5000 N, the mass is 1000 Kg so deceleration is
a = 5000 / 1000 = - 5 m/^2 [note the minus sign]
Recall from the equations of motion that
V^2 = U^2 + 2 a x
where V = final velocity (m/s); U = initial velocity (m/s); a = acceleration; x = distance
Here, the final velocity will be zero when it comes to rest, so
0 = 36^2 - (2 * 5) x = 1296 - 10x
10x = 1296
x = 1296 / 10 = 129.6 m

I think its just 500N of tension.
