Question

What is the mass of a 4900 N bobsled

Answer 1

Answer:

500 Kg.

Explanation:

The problem is giving us the weight of the object the weight is different from the mass of an object

Weight is the mass of any object multiplied by gravity (the value of gravity is approximately  $9.8\frac{m}{s^2}$ ).

The unit of weight are newtons that equals

$N= Kg.\frac{m}{s^2}$

$W= m.g$

we cleared the mass of the formula

$W=m.g\\ m=\frac{W}{g} \\ m= \frac{4900N}{9.8 \frac{m}{s^2} }= 500 Kg$

Answer 2

A single kilogram is equivalent to 9.8 newtons, meaning that to find the weight of the bobsled, you would simply divide the weight by 9.8. Doing this we find that the bobsled is 500kg

4900 / 9.8 = 500
