The final momentum of the ball is 3.8 kgm/s.
<h3>Change in momentum of the ball</h3>
The impulse received by the ball is equal to change in momentum of the ball.
J = ΔP
where;
- J is the impulse
- ΔP is change in momentum
ΔP = P₂ - P₁
P₂ = ΔP + P₁
<h3>Final momentum of the ball</h3>
The final momentum of the ball is calculated as follows;
P₂ = 8 + (- 0.1 x 42)
P₂ = 8 - 4.2
P₂ = 3.8 kgm/s

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

Answer:
The Three Mountain Task was developed by Jean Piaget and Bärbel Inhelder in the 1940s to study children's ability to coordinate spatial perspectives. In the task, a child faced a display of three model mountains while a researcher placed a doll at different viewpoints of the display.
