A man fell out of an airplane and barely survived. He was moving at a speed of 100m/s just before landing in deep snow on a mountain side. Experts estimated that the average net force on him was 600 N as he plowed through the snow for 10 s. What was his mass, in kg

Respuesta :

Answer:

Mass in kg will be 60 kg

Explanation:

We have given initial speed of the man u = 100 m/sec

And final speed v = 0 m/sec

Time is given, t = 10 sec

So acceleration [tex]a=\frac{v-u}{t}=\frac{0-100}{10}=-10m/sec^2[/tex]

Force is given , F= 600 N

From Newton's law we know that F = ma

So [tex]600=m\times 10[/tex]

mass = 60 kg

So mass in kg will be 60 kg
