Explanation:
We have,
Mass of a wrench, m₁ = 4 g = 0.004 kg
Speed of wrench, v₁ = -15 m/s
Mass of the Astronaut, m₂ = 70 kg
It is required to find Astronaut's velocity. Let it is v₂. Using the conservation of linear momentum to find it.
So, his velocity is .
Complete Question
A baseball is thrown horizontally with an initial speed of 10 m/s from the edge of a cliff. A stop watch measures the ball's time in the air until it hits the ground to be 4.3 s. How far does the baseball travel horizontally?
Answer:
The distance covered horizontally is
Explanation:
From the question we are told that
The initial horizontal velocity is
The time taken by the ball in the air is
Generally the distance traveled by the ball is
