Answer:
The net force acting on that object must be 0
Explanation:
According to Newton's first law of motion, if there's no force acting on an object (or the net force is 0), that object will stay at the same speed. That object acceleration must also be 0.
I believe these are the answers
#1- D
#3-B
#4- D
#5- D
#6-A
#7-B
I was able to get everything except #3
I hope this helps though :)
Answer:
1.8 Kg 17.6N
Explanation:
I don't know the explanation hahaha
Explanation:
The magnitude of centripetal acceleration is:
a = v² / r
The velocity is:
v = d/t
v = 2 × 2π (5 m) / 60 s
v = 1.05 m/s
a = (1.05 m/s)² / (5 m)
a = 0.219 m/s²
The direction is towards the center. So at point A, the centripetal acceleration is 0.219 m/s² downward, and at point B, the centripetal acceleration is 0.219 m/s² upward.
Answer:
A balloon is floating up into the air at 1 m/s.
Explanation:
Velocity is the displacement divided by the time;
Velocity =
It is a vector quantity that has magnitude and direction.
The choice that shows a change in direction is a correct specification of velocity.
A balloon floating up into the air at 1m/s shows no directional change.
