# Question #bb36d

##### 1 Answer

The second boat has a mass of **2670 kg**.

#### Explanation:

You know that force is equal to *mass* multiplied by *acceleration*.

Notice that, compared with the acceleration of the first boat, the acceleration of the second boat dropped significantly.

Since the force acting on the two boats is *unchanged*, this implies that the mass of the second boat must be **significantly bigger** than the mass of the first boat.

Mathematically, you can write

Since the same force acts on both boats, you can also write

As a result, you have

Solve this equation for
