The answer is c, but I'm not sure, just so you know
Answer:
63360 mi/h
Explanation:
<u>How to find the speed of an object</u>
Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown SDT value given two known values.
Time can be entered or solved for in units of second S (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm: ss). See shortcuts for time formats below.
To solve for distance use the formula for distance D = st, or distance equals speed times time.
distance = speed x time
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
distance = rate x time
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
speed = distance/time
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
time = distance/speed
Therefore, the speed = 63360 miles per hour
= 63360 mi/h
The distance the object willl fall durring the 2nd seconds is 4.9 m
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Initial velocity (u) = 0 m/s
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 2 - 1 = 1 s
- Height (h) =?
<h3>How to determine the distance the object will fall during the 2nd seconds</h3>
The distance the object will fall during the 2nd seconds can be obtained as follow:
h = ut + ½gt²
h = (0 × 1) + (½ × 9.8 × 1²)
h = 0 + 4.9
h = 4.9 s
Thus, the distance the object will during the 2nd seconds is 4.9 m
