Answer
The apple is traveling at 8 meters per second
Explanation
We have the equation that relates the kinetic energy with the velocty:

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

Thus, the speed of the apple is 8meter per second
18:24 = 3/4
4:70 = 2/35
35:105 = 1/3
22:7 = 22/7
12:165 = 4/55
Given:
difference in the mean weight gain is 0.60 grams
standard deviation of the difference in sample mean is 0.305
68% confidence interval for the population mean difference is a) 0.305
0.60 <u>+</u> 1 * 0.305
0.60 + 0.305 = 0.905
0.60 - 0.305 = 0.295
95% confidence interval for the population mean difference is c) 0.61
0.60 <u>+</u> 2 * 0.305
0.60 + 0.61 = 1.21
0.60 - 0.61 = -0.01
45 multiply 0.22 = 9.9
45-9.9 = 35.1
