The dogs of four-time Iditarod Trail Sled Dog Race champion Jeff King pull two 100-kg sleds that are connected by a rope. The sl

azamat

Answer:

Part a)

$a = 2.4 m/s^2$

Part b)

$F = 120 N$

Explanation:

Two sleds are connected by a rope

mass of each sled is given as

$m = 100 kg$

now we know that dog exert pulling force on the rope connected to first sled

$F = 240 N$

Part a)

By newton's first law we know that

$F = (m + m)a$

$240 = (100 + 100)a$

$a = \frac{240}{100}$

$a = 2.4 m/s^2$

Part b)

As we know that force between two ropes will pull the sled behind

so we will have

$F = ma$

$F = 100(1.20)$

$F = 120 N$
