Yes for #1
We used d=½gt² rounding up to 10 for g.
For #2.
The answer is looking for the delta mv for the 3 s free fall. I used
Ft= 🔺️ mv
F(3)= 🔺️ (100 kg) (30 m/s)
F(3)= 3000 kg • m/s
For #5. Looking for the force. I used
F=m( vi-vf)/t
F=100kg(30m/s-0)/2s
F=100kg(30m/s)/2s
F=1500N
I...
Thank you all for your help. A few hours sleep made a big difference as well. While my screen name does say Academy please know I do not have an actual Academy- I am a mother who happens to have 2 teens who homeschool. They wanted to take a physics class.
As many of you know science is more...
For question 1.
I am stuck. I know that the equation involves time and possibly rate, should solve for distance. But not sure how to set it up with information given.
2. Ft= m 🔺️ v
F(3)= (100kg)(30m/s)
3 s= 3000 kg m/s
Same applied to question 3.
3. F(2)= (100kg)(-30m/s)
F(2) = -3000 kg m/s...
