The waste products of combustion leave the internal combustion engine through the

A. cylinder.

B. intake valve.

C. crankshaft.

D. exhaust valve.

D. Exhaust valve.

Explanation:

An exhaust valve is a valve controlled by the camshaft that allows burned gases and other combustion products to exit the combustion chamber.

The burned gases exit the chamber so that fresh air can come into the combustion chamber so as to repeat the combustion process over and over again.

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
