Given,
Kinetic energy of the car = 2000 J
speed of the car is doubled
we know,
now, speed of the car is doubled
v' = 2 v
Using
=1/22
Hence, the Kinetic energy would be equal to 8000 J.
OPTION D is the correct answer.

Answer:
0.025 m
Explanation:
From the question,
Applying Hook's law
F = ke................... Equation 1
Where F = Force, k = spring constant of the scale, e = maximum distance at which the spring will compress.
make e the subject of the equation
e = F/k....................... Equation 2
Given: F = 10 N, e = 395 N/m
Substitute these values into equation 2
e = 10/395
e = 0.025 m
Answer:
Answer:
f) The puck conserves its original momentum but loses some, but not all, of its mechanical energy.
Explanation:
It is a case of perfectly inelastic collision . So momentum will be conserved because no external force acts on them during the collision . But there will be loss of energy ( kinetic energy ) . It will be in the form of sound or heat that is produced during collision. They will still have some kinetic energy even after the collision.
