A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of 11 m/s in a time of 28 s. The combined mass of the boat and trailer is 410 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car

Respuesta :

The tension on the hitch that connects the trailer to the car is 160 N.

From the information provided;

Initial velocity = 0 m/s (the car started from rest)

Final velocity = 11 m/s

Time taken = 28 s

From the formula;

a = v - u/t

a = 11 - 0/28 = 0.39 ms-2

The force that acts on the trailer  = tension in the hitch that connects the trailer to the car

Force = mass × acceleration

Force = 410 kg × 0.39 ms-2

Force = 160 N
