Answer:
Explanation:
Project mass m=3.8 kg
Initial speed vi= 0m/s
Final speed vf= 9.3×10³ m/s
Force F=9.3×10⁵N
To find
Time t
Solution
From Newtons second law we know that
∑F=ma
Where m is mass
a is acceleration
We can write this equation as
∑F=m(Δv/Δt)
Rearrange this equation to find time t
So
Substitute the given values
F=m*a
F=65 kg *9.8 m/s^2
F=637 N (Newtons) — this is the weight
Answer:
Maybe put them in order ????
Explanation:
<h2>Answer</h2>
The force will be doubled.
<h2>Explanation</h2>
Using Newton Law II,
<h3>F = ma </h3>
So it can be seen in the formula that force is directly proportional to mass and acceleration.
if mass is doubled ---> force will be doubled, keeping acceleration constant.
Similarly,
if acceleration is doubled ---? force is will be doubled, keeping mass constant.
