The red at the bottom is just the holder for the beaker. It’s not apart of the density.
Answer:
1.736m/s²
Explanation:
According to Newton's second law;
where;
Fm is the moving force = 70.0N
Ff is the frictional force acting on the body
is the coefficient of friction
m is the mass of the object
g is the acceleration due to gravity
a is the acceleration/deceleration
The equation becomes;
Substitute the given parameters
Hence the deceleration rate of the wagon as it is caught is 1.736m/s²
I think by using data collected by Tycho Brahe
It might be 4.0 or 2.22344 seconds as velocity speed
