Two masses, MA and MB, with MB = 2MA, are released at the same time and allowed to fall straight down. Neglect air resistance. When we compare their kinetic energies after they have fallen for equal times, we find thata. KB =KA.
b. KB =2KA.
c. KB =4KA.
d. KA =2KB.
e. KA =4KB.

In 1980, alfa romeo introduced the first system to smooth a rough idle caused by ignition and camshaft timing changes.
