A cannon tilted upward at θ = 35 ∘ fires a cannonball with a speed of 100 m/s .

At that instant, what is the component of the cannonball’s velocity parallel to the ground?

Express your answer using two significant figures.

Anybody wanna ? (picture included? )

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
