Question

Two horses, Thunder and Misty, are accelerating a wagon 1.3 m/s2. The force of friction is 75 N. Thunder is pulling with a force of 1,000 N, while Misty is pulling with a force of 800 N. The force of gravity is 14,700 N and the normal force is 14,700 N. What is the mass of the wagon? Round the answer to the nearest whole number.

Answer 1

1327 is right

Step-by-step explanation:

yes

Answer 2

1327 kg

Step-by-step explanation:

So the net force exerted on the wagon would be the sum of forces from 2 horses subtracted by friction force

`F = 1000 + 800 - 75 = 1725 N`

This force results in an acceleration of a = 1.3 m/s2. We can use Newton's 2nd law to calculate the mass of the wagon

`F = ma`

`m = F / a = 1725 / 1.3 \approx 1327 kg`
