(Answered) Britney spears is on stage in vegas being acted upon by

Academics

Britney Spears is on stage in Vegas, being acted upon by gravity, maybe even a backup dancer.

Here are Britney's positions over a specific time interval:

INTERVAL A

5.45 s <3.43, .91, 5.65> m

5.50 s <3.62, .91, 5.84> m

INTERVAL B

6.45 <6.72, .91, 10.34> m

6.50 <6.83, .91, 10.45> m

1. What is Britney's average momentum over INTERVAL A? Her mass about 115lbs, or 52kg.

2. What is Britney's average momentum over INTERVAL B?

3. What is the average net force acting on Britney from 5.45 to 6.45?
