Answer:
3. 3.5 s
Explanation:
The position of traveller A is given by the equation:
where
is the acceleration of A
t is the time measured from when A started the motion
The position of traveller B instead is given by
where a (acceleration) is the same as traveller A, and
is B's initial velocity. We can verify that the formula is correct by substituting t=2, and we get 
, which means that B starts its motion 2 seconds later.
Traveller B overtakes traveller A when the two positions are the same, so:
acceleration = change in velocity /change in time
convert 40km to meter then divide it with 5
Answer:
a) 6.95 m/s
b) 1.42 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
a) The vertical speed when it leaves the ground. is 6.95 m/s
Time taken to reach the maximum height is 0.71 seconds
Time taken to reach the ground from the maximum height is 0.71 seconds
b) Time it stayed in the air is 0.71+0.71 = 1.42 seconds
<h3>Answer: any path that allows electrons to flow</h3>
An electrical circuit is a path in which electrons from a voltage or current source flow. ... The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".
