Answer:

C. 3m/s

Explanation:

Since we ignore air resistant, horizontally speaking, theres no force acting on the ball. According to Newton's 1st law of motion, when there's no force, the object will stays in the same velocity.

In this case after, the ball velocity would still be 3m/s

Calculate the potential energy at the top of the giant drop if the car weights 1000 kg
bonufazy [111]
The gravitional potential energy, relative to the bottom of the giant drop, in joules, is (9800) times (the height of the drop in meters). That's the PE of the empty car only, not counting any hapless screaming souls who may be trapped in it at that moment.

Help !!!! Estimate the number of breaths taken by a person during 44 years?
Lisa [10]
44 x 12. I got the 12 from the total of 12 months in a year.


44 > 40

x
12 > 10
----------
The way my teacher taught me how to estimate is look at the neighbor to 44 and 12. The only time 44 can become 50, is when the neighbor is 5 or up. Same thing for 12. Now, multiply 40 and 10.

40 x 10 = 400.

Therefore, your estimate is 400.

The real answer is 520 breaths.
