The answers to the Speed question are:
Speed is known to be the distance that is said to be traveled and it is per unit of time. It is seen as the rate of which an object is said to be moving.
Note that Speed is calculated in this case as 1/2mv².
Therefore, to calculate the variables are:
If the speed of the bottle is 2 m/s, then
= ½ (0.250) (2) ^2
= 0.5
If the speed of the bottle is 3 m/s, then
= ½ (0.250) (3) ^2
=1.125
If the speed of the bottle is 4 m/s, then
= ½ (0.250) (4) ^2.
= 2
If the the speed of the bottle is 5 m/s, then
= ½ (0.250) (5) ^2
= 3.125
= ½ (0.250)(6)^2
=4.5
Therefore, the answer given above are correct.
