A soccer ball is kicked at an angle of 30° to the horizontal with an initial velocity of 16 m/s. How high does the soccer ball g
Ugo [173]
Vertical component of velocity = 16sin(30°) = 8m/s

at the highest point of flight, the velocity of the ball is 0 (that moment when it stops before starting to fall) so:
v^2=u^2+2as<u />
0^2=8^2+(2\times-9.81\times s)
s= \frac{0^2-8^2}{2\times-9.81}<u />
s=3.26m

So rounding up gives option B. (3.3m)

babymother [125]

Answer:

Option (B)

Explanation:

A lift chart usually refers to a graphical representation that is mainly used in order to improve the drawbacks of a mining model by making a comparison with any random guess, and also helps in determining the changes that occur in terms of lift scores.

It describes the binary classification of the problems associated with the mining activity. This type of chart is commonly used to differentiate the lift scores for a variety of models, and picking the best one out of all.

Thus, the correct answer is option (B).

When driving on a multilane street with two way traffic:?
koban [17]
When driving on multilane street with two way traffic, the best response to this scenario is to drive ahead but if there are vehicles in front of you, it is also best to drive along behind the multilane vehicles. It is not best to over take or to consume the middle lane because it is a multilane street. In which there are only two lanes and over taking it could cause accidents when not careful, and consuming up the middle is not appropriate to take because the lane is for two lanes.
