Explanation:
It is given that,
Mass of cardinal,
Mass of baseball, 
Both cardinal and baseball have same kinetic energy. We need to find the ratio of the cardinal's magnitude
of momentum to the magnitude
of the baseball's momentum.

Kinetic energy is given by, 




So, 
So, the ratio of cardinal's magnitude of momentum to the magnitude of the baseball's momentum is 53 : 100
Answer:
748.8 kJ
Explanation:
Kinetic energy is given by
where m is the mass of the body, v is the velocity
Substituting 2600 Kg for m and 24 m/s for velocity

Therefore, kinetic energy is 748.8 kJ
Answer:
Explanation:
Wheel completes four revolution.
The linear displacement is zero.
The angular displacement is 4 x 2π = 8π radian.
So, option (c) is correct.
It’s A .
- correct me if i’m wrong -
C. transform energy into a different from.
I hope this helps
