Answer:
The average velocity of the rock would be 32 ft per second.
Step-by-step explanation:
A rock has been dropped from a height of 64 ft.
Height of the rock is determined after time 't' by the expression.
S(t) = -16t² + 64
Where 0 ≤ + ≤ 2
Total distance traveled by the rock in
2 seconds = 64 feet
Therefore average velocity = = 32 ft per second
The average velocity of the rock would be 32 ft per second.
Answer:
25
Step-by-step explanation:
60 = 15
100 = x
now cross multiply so 100*15 is 1500 now divide it by 60 which is 25
7.8 x 100 = 780
7.83 x 10,000 = 78,300
