I believe the answer is a. Because the formula of kinetic energy is 1/2(m)•(v^2)
Explanation:
the formula for momentum is denoted by p=mv where p is momentum, m is mass and v is velocity. thus, the velocity before impact would be 0.060 x 30 = 1.8 kg/ms
the second one would just be 0.060 x 20 0.72kg/ms
I'm not 100 percent sure this is correct but yeah
Answer:
a) the velocity increases then decreases.
