Answer is given below
Explanation:
given data
pressure = double
volume = constant
solution
As we know that an Average velocity and rms velocity is directly proportional to square root of PV ..................1
so if we take P is doubled while keeping V constant
than Velocity increases by a factor
so that Factor = 1.414 for both the cases
Answer:
The detailed calculations are shown below;
Explanation:
a)The maximum acceleration of the particle:
It is seen that the maximum change in velocity is at the time between 8s to 10s.
Maximum acceleration:
=
= 10 m/
b) The deceleration of the particle
The velocity of particle is decreased after 10s so,
deceleration = -
= - 6.67 m/
c)The total distance traveled by the particle = Area under the curve
= * 4*20 + 4*20 +
* 2*20+ 2*20+
* 40*16
= 290 m
d)The average velocity of the particle =
=
= 18.12 m/s
