Explanation:
2.5 Mg = 2500 kg
The change in speed from 100 km/h to 40 km/h is
The deceleration caused by friction force is the change in speed per unit of time
Using Newton 2nd law we can calculate the friction force that caused this deceleration:
F = ma = 2500 * 3.33 = 8333 N
Let g = 9.8m/s2. Friction force is the product of normal (gravity) force and friction coefficient
Answer:
Explanation:
= Initial pressure =
= Initial volume
= Final volume =
Temperature is the same in the initial and final state
From the ideal gas law we have
The final pressure of the system is .
