Explanation:
I'm working for your organisation in London as the company
Here, S = ut + 1/2 at²
381 = 0*t + 1/2 * 9.8 * t²
762/9.8 = t²
t = √77.75
t = 8.82 sec
In short, Your Answer would be 8.82 s
Hope this helps!
Answer:
21.67 m/s²
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 49.7 m/s
Radius (r) = 114 m
Centripetal acceleration (a) =?
The centripetal acceleration can be obtained by using the following formula:
a = v²/r
a = 49.7² / 114
a = 2470.09 / 114
a = 21.67 m/s²
Therefore, the centripetal acceleration of the car is 21.67 m/s²
Answer: the correct option is D (17m).
Explanation: The farthest distance at which a typical "nearsighted" frog can see clearly in air is 17m.
