Answer:
3 m/s
Explanation:
Answer:3m/s
mass(m)=50kg
Kinetic energy =225 joules
Kinetic energy=(m x (velocity)^2)/2
225=(50 x (velocity)^2)/2
Cross multiplying we get
225x2=50x(velocity)^2
450=50x(velocity)^2
Divide both sides by 50
450/50=(50x(velocity)^2)/50
9=(velocity)^2
Taking the square root of both sides we get
√9=velocity
3=velocity
Velocity=3m/s
step by step explanation
A! I already went through this unit. Joule.
= 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 .
