You have a distance and a time so you can work out the bikes speed which would be distance/time so 40mph.
answer C is the correct one
Answer: d. 5 m/s^2
Explanation:
Acceleration is the change in velocity in a given time.
a = (30-20)/2 = 5
Explanation:
The given data is as follows.
Concentration of caffeine = 2.97 mg/oz
Number of oz in a can = 12 oz
Therefore, the concentration of caffeine in one can is calculated as follows.
=
mg
= 35.64 mg
= 
Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.
No. of cans = 
= 
= 280.58
= 281 (approx)
Thus, we can conclude that 281 cans of soda would be lethal.
His new number should be: 239.2 Liters
