Question

Use g = 9.8 m/s2. On Earth, an astronaut and equipment weighs 2,030 N. While weightless in space, the astronaut fires a 160 N rocket backpack for 1.1 s. What is the resulting velocity of the astronaut and equipment?

Answer 1

The resulting velocity is 0.85 m/s

What is Gravitational Force ?

The force of attraction between all bodies in the universe is called Gravitational Force.

It is given in the question that

Weight of Astronaut and Equipment on Earth = 2030 N

The mass of the Astronaut and Equipment is

F =m * a

g = 9.8 m/s²

=2030/9.8

= 207.14 kg

The change in the momentum is given by

P₂-P₁  = force * time

There is no initial velocity , therefore initial momentum is zero

mv- 0 = Force *time

207.14 * v = 160 * 1.1

v =0.85 m/s

Therefore the resulting velocity is 0.85 m/s
