Question

your friends sit in a sled in the snow. If you apply a force of 120 N to them, they have an acceleration of 1.3 m/s^2.what is their mass?

Answer 1

Answer:

Mass of the sled, m = 92.30 kg

Explanation:

It is given that, your friends sit in a sled in the snow.

Force applied on the sled, F = 120 N

Acceleration, $a=1.3\ m/s^2$

We need to find the mass of the sled. The force acting on the sled is equal to the mass of the sled and the acceleration produced i.e.

$F=ma$

$m=\dfrac{F}{a}$

$m=\dfrac{120\ N}{1.3\ m/s^2}$

m = 92.30 kg

So, the mass of the sled is 92.30 kg. Hence, this is the required solution.

Answer 2

The formula to use is:
$f = m \times a$
Using the given numbers this makes:
$120 = m \times 1.3 \\ m = 120 \div 1.3 = 92.3 kg$
