Question

what is the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg

Answer 1

Answer:

The acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².

Explanation:

Given

• Force F = 4000 N

• Mass m = 1240 kg

To determine

Acceleration a = ?

Important Tip:

• The acceleration of a boat can be found using the formula F = ma

Using the formula

$F = ma$

where

• F is the force (N)

• m is the mass (kg)

• a is the acceleration (m/s²)

now substituting F = 4000, m = 1240 in the formula

$F = ma$

$4000\:=\:1240\:\times a$

Switch sides

$1240a=4000$

Divide both sides by 1240

$\frac{1240a}{1240}=\frac{4000}{1240}$

Simplify

$a=\frac{100}{31}$

$a=3.2$ m/s²

Therefore, the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
