An integrated circuit, also known as a chip, is mounted on a circuit board.

True. An integrated circuit (IC) is an electronic circuit which mounted on  a small chip made from a semiconducting material like silicon or germanium. It's is like the electronic circuit made from discrete components but smaller in size. It's example is a microprocessor.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
