HELP I HAVE A TEST IN AN HOUR Nine dogs are pulling a sled in a race. The combined mass of the sled and the driver is 220 kg.
(a) The dogs start from rest and reach a speed of 5.0 km/h in 8.0 s. What is the average force applied by each dog?
(b) What is the frictional force on the sled if each dog is pulling with a maximum force of 51 N?

957.4845 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

Time taken by the thunderbird to stop is 6.993 seconds

Time the thunderbird was at the pit is 5 seconds

Time taken to accelerate back to 71.5 m/s is 9.79 seconds

Total time to this point is 6.993+5+9.79 = 21.783 seconds

The Mercedes Benz is moving at a constant velocity hence it has no acceleration and we use the formula

Distance = Speed × Time

⇒Distance = 71.5 × 21.783 = 1557.4845 m

The thunderbird has covered 250+350 = 600 m

So, the distance between them is 1557.4845-600 = 957.4845 m
