Answer:
The fraction of the ball's kinetic energy stored in the spring is 3.6KJoules
Explanation:
Given
Mass of ball =0.5kg
Velocity of ball =120m/s
The kinetic energy stored by the ball is expressed as
K.E=1/2(m*v²)
Substituting our data into the expression we have
K. E=(0.5*120²)/2
K. E=7200/2
K.E=3,600 JOULE
K.E=3.6KiloJoules
Answer:
The skier's change in velocity is 7.69 meters per second.
Explanation:
The Newton's second law tells force is equal to the change on the linear momentum of a body:
If we approximate the differential 
to 
:
Using that linear momentum is mass times velocity:
Solving for 
:
