(a) time taken for the car to accelerate from v to 2v = t =
(b) velocity of the car moving at 2t seconds = ΔV = 2at
(a) we know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
Time taken to accelerate from V to 2V:
t =
(b) We know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
how fast is the car moving at 2t seconds after starting,
we can represent - = ΔV
at time = t= 2t, it becomes
a= = a = ΔV/2t
t= ΔV/2a
ΔV = 2at
<h3>What is acceleration?</h3>
Rate of change of velocity with time, both in terms of speed and direction is known as acceleration.
<h3>What is speed?</h3>
- the rate at which an object's location changes in any direction.
- The distance traveled in relation to the time it took to travel that distance is how speed is defined.
- Since speed simply has a direction and no magnitude, it is a scalar quantity.
