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

Answer:
Conduction is the main method of thermal energy transfer in solids.
Hope this helps.....
Answer:
78.6m/s
Explanation:
We know that frictional force also contributes to the centripetal force that keeps the car in circular motion in the turn
And is given as
F= mv²/r
But the frictional force is
F= ugm
= = 0.7*1200*9.8= 8232N
To find maximum velocity v we say
V= √F x r/m
= √ 8232* 90 /1200
= 78.6m/s
2. Yes it is independent of mass of car
