Answer:
This is True
Explanation:
I just did this exact unit in bio last week I hope this helps ;)
For the answer to the question above, we'll have to use these formulas.
A) to find time to travel the 300m,
just find horizontal component of the velocity and divide.
ie x=89 x t x cos 40, t=x/89 x cos 40
<span>B) y=vtsin 40 - gt^2/2, just sub in
</span>
I believe you can do the rest.
I hope I helped you with my answers.
882 divided by 9.81 (this is acceleration due to gravity) it equals 89.91
Answer:
Explanation:
Suppose when bucket is half full it has a mass of 2 m rotating in a circle of radius r
When Bucket is quarter full then it has a mass of m rotating in a circle of radius r.
When an object moves in a circular path then it experiences an inward force which is given by
where v=velocity of bucket
Force in case 2 is given by
Thus 
therefore force required in half bucket is more than force required in quarter bucket full.
Answer:
As we have already discussed earlier, motion is the state of change in position of an object over time. It is described in terms of displacement, distance, velocity, acceleration, time and speed. Jogging, driving a car, and even simply taking a walk are all everyday examples of motion. The relations between these quantities are known as the equations of motion.
