Sorry, I most likely did this wrong; but hopefully I didn't!
HgO2
Na+H2CI
K2CI2
C2H6O2--> H2CO2
C5H12O2--> H2CO3
Answer:
<h3>The answer is 7 kg</h3>
Explanation:
To find the mass of the object given the force and acceleration we use the formula
where
f is the force
a is the acceleration
m is the mass
From the question
f = 49 N
a = 7 m/s²
We have
We have the final answer as
<h3>7 kg</h3>
Hope this helps you

Answer:
V=15.3 m/s
Explanation:
To solve this problem, we have to use the energy conservation theorem:
the elastic potencial energy is given by:
The work is defined as:
this work is negative because is opposite to the movement.
The gravitational potencial energy at 2.5 m aboves is given by:
the gravitational potential energy at the ground and the kinetic energy at the begining are 0.
