The two forces shown act in the x-y plane of the t-beam cross section. if it is known that the resultant r of the two forces has a magnitude of 2.9 kn and a line of action that lies 17° above the negative x-axis, determine the magnitude of f1 and the orientation θ of f2.

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?
