I don't understand this question​

Acar with a mass of 600 kg is traveling at a velocity of 10m/s. how much kinetic energy does it have?

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?
