Answer:
4m/s approx
Explanation:
Step one
Given data
m1=71kg
m2=65kg
v1=3.4m/s
v2=??
We are required to find the Velocity of the second person
By applying the conservation of momentum principles
P=mv
m1v1=m2v2
Substitute
71*3.4=61*v2
241.4=61v2
Divide both sides by 61
v2=3.95m/s
v2=4m/s approx
Answer:
Yes, extrapolated value do agree with accepted value of free-fall acceleration
Explanation:
Extrapolated value of acceleration up to 90 degree is accepted. There is an existing equation relating the acceleration of a body moving down a frictionless incline plane and the angle of inclination.
acceleration of the object is proportional to sine of the angle of inclination and the acceleration due to gravity. a=gsin(θ)
The value can be derived by calculating the acceleration at different angle of inclination and comparing the trend.
I will answer the ones I know...and hopefully these help!..
1). Gravity makes the object fall towards the ground! It’s the gravitational pull that brings the object back down
These motions have to do with Newton’s third law..
3). I don’t think so but I might be wrong
Cuz I think that since Earth has a large mass, it pulls things in towards it but they orbit.
Sorry if that’s wrong!
-hope I helped in a way!
Wished I coulda answered all of em
