Answer:
Explanation:
Given
mass of climber
Distance between rock and cliff=48.6 m
mass of rock
let T be the tension in the rope
Thus ------1
where a is the acceleration of system
Also for Rock
------2
From 1 & 2 we can say that
g+a=19.303 a
g=18.303 a
Thus climber is decelerating with
time to cover 48.6 m
t=13.47 s
A bullet with mass 60.0 g is fired with an initial velocity of 575 m/s from a gun with mass 4.50 kg. The speed of the recoil of the gun is

So basically the objects would be sandpaper and smooth metal, the sandpaper can indirectly touch the metal since it’s so smooth and it won’t cause any temp change either
The answer is A. The ball exerts an equal backward force on the racket. Newton’s 3rd Law: to every action there is an equal and opposite reaction.
