Both vehicles experience the same change in momentum.
When the compact car rear ends a truck, they exert equal forces on each other, in accordance with Newton's third law. The force exerted by the car on the truck is equal to the force exerted by the truck on the car.The force acting on the two bodies act for the same interval of time.
According to Newton's second law, the force acting on a body is equal to the rate of change of momentum.
Since the forces are equal,

therefore, the change in momentum of the car
is equal to the change in the momentum of the truck
.
Thus, both the car and the truck experience the same change in their momentum. However due to the smaller mass of the car, the change in its velocity is greater than the change in the truck's velocity, which has a larger mass.
Answer:
The observer sees the space-probe 9.055m long.
Explanation:
Let
be the length of the space-probe when measured at rest, and
be its length as observed by an observer moving at velocity
, then

Now, we know that
and
, and putting these into
we get:


Thus, an observer moving at 0.95c observes the space-probe to be 9.055m long.

a. Final pressure= 5atm
b. Work done = 5000 Joules
<h3>How to determine the parameters</h3>
Given;
- Temperature = 330K
- P1 = 6 atm
- V1 = 500cm^3
- V2 = 1500cm^2
In adiabatic expansion, temperature is constant
P1V1 = P2V2
Now, let's substitute the values into the formula
6 × 500 = 1500 P2
300 = 1500P2
Make 'p2' subject of formula
P2 = 1500/300
P2 = 5 atm
The formula for work done is given as:
Workndone = P ∆ volume
Work done = 5 × ( 1500 - 500)
Work done = 5 × 1000
Work done = 5000 Joules
