He most likely can use a generator
Answer:
(c) 19.0s
Explanation:
Given Data
Car A speed v=22.0 m/s
Car B speed v=29.0 m/s
Car A distance S=300 m behind Car B
Car A acceleration a=2.40 m/s²
To find
Time required For Car A to take over Car B
Solution
We can represent Car A Coordinate by using equation of simple motion

And Coordinates of car B equals

Car A is overtake car B when:

Option (C) 19.0s is correct one
The correct answer is C.
We will use Boyle's law that states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
P1 V1 = P2 V2
Where
P1 is initial pressure = 5 psi
V1 is initial volume = 20 cubic inch
P2 is final pressure = 10 psi
V2 is final volume = unknown
V2 = P1,V1 / P2
V2 = 20 × 5 / 10
V2 = 100/10
V2 = 10 cubic inches
