Everything on this page is solved with the SAME formula !
Distance = (speed) x (time) .
Before I get into how to solve each problem, we need to notice that
this whole sheet deals with speed, NOT velocity.
'Velocity' is speed AND THE DIRECTION OF THE MOTION.
Nothing on this page ever mentions direction, so there's no velocity
anywhere on the page.
Your teacher may not be happy if you talk about this on your homework,
but that's too bad. Just don't say "velocity" in any of your answers.
Say "speed", and if the teacher complains about that, then it's time to
let the teacher have it with both barrels.
1). Speed = (distance covered) / (time to cover the distance)
2). Speed = (distance covered) / (time to cover the distance)
3). Distance = (average speed of travel) x (time traveling at that speed)
4). Time to cover the distance = (distance) / (speed)
5). Car's speed = (distance the car covered) / (time the car took)
Sprinter speed = (distance the sprinter covered) / (time the sprinter took)
Calculate the car's speed.
Calculate the sprinter's speed.
... Look at the two speeds.
Decide which one is faster.
... Subtract the slower one from the faster one.
The difference is the answer to "by how much?" .
6). Distance = (speed) x (time spent moving at that speed)
7). Average speed = (TOTAL distance covered)
divided by
(time to cover the TOTAL distance).
I disagree that folk dance forms can be outside their original meaningful form in this scenario.
<h3>What is Folk dance?</h3>
This is the type of dance which is unique to a particular set of people and helps celebrate their culture.
This dance is a ritualistic entertainment which is done in different type of gatherings such as ceremonies etc which is why it isn't outside their original meaningful form.

Answer:
the velocity (magnitude and direction) of the ball) just before the collision is 
The velocity (magnitude and direction) of the ball) just after the collision is 
Explanation:
According to the law of conservation of energy;
Thus; the velocity (magnitude and direction) of the ball) just before the collision is
Since, Air resistance is negligible, and the collision is elastic.
The equation for the conservation of momentum and energy can be expressed as:
![v_f = [\frac{m_1 -m_2}{m_1+m_2}]v_i\\\\v_f = [\frac{m_{ball} -m_{block}}{m_{ball}+m_{block}}]v_i\\\\v_f = [\frac{1.6 -2.5}{1.6+2.5}]*5.144\\\\](https://tex.z-dn.net/?f=v_f%20%3D%20%5B%5Cfrac%7Bm_1%20-m_2%7D%7Bm_1%2Bm_2%7D%5Dv_i%5C%5C%5C%5Cv_f%20%3D%20%20%5B%5Cfrac%7Bm_%7Bball%7D%20-m_%7Bblock%7D%7D%7Bm_%7Bball%7D%2Bm_%7Bblock%7D%7D%5Dv_i%5C%5C%5C%5Cv_f%20%3D%20%5B%5Cfrac%7B1.6%20-2.5%7D%7B1.6%2B2.5%7D%5D%2A5.144%5C%5C%5C%5C)
