DetailsThe P value for this will be very high. If I calculate this, we will look for zero point by 98 approximately comes out to be 0.274 So this is my normal distribution. This is 0.60 point six. This area is 60.274 So the zero point 274 So this is not unusual. This is my Z statistic. And if I want to find the area, this is my area approximately.
DetailsVIDEO ANSWER:Hello students in this question we have given that a dynamic blast at a quarry launches, a rocky state upward and after the time of 2.4 seconds, it is rising at 18 meter per second so launch speed. That is initial speed. We have to determine so from the first equation of motion. It is equal to u minus of gay. So, u will be v, which is 18 meter …

DetailsOct 04, 2017· Speed at launch would be 0 m/s because it can be assumed the rock was stationery at the time of the blast, though there is no information specifying this to be true. The speed after 6 seconds would be calculated at distance over time squared. So acceleration is assumed to be 5.65m/s. After 6 seconds this would be 33.9m/s

DetailsVF is 12, so V I is 12 plus 9.8 times 1.6 seconds and we get 27.68 m per second For this. For part B 4.5 seconds, we need to first find the time to reach the maximum height, which is VI divided by G or 27.68, divided by 9.8, which is 2.82 seconds. So when T is 4.5 is going downwards, so T prime is 4.5 minus 2.82, which is 1.68 seconds.
