(a) \( 0.144 \mathrm{~km} / \mathrm{s} \) (b) \( 1.7 \mathrm{~km} / \mathrm{s} \) (c) \( 0.6 \mathrm{~km} / \mathrm{s} \) (d) \( 1.2 \mathrm{~km} / \mathrm{s} \) (e) \( 0.85 \mathrm{~km} / \mathrm{s} \) 2) A truck travels due west with a speed of \( 90.0 \mathrm{~km} / \mathrm{h} \). Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the truck make an angle of \( 37.0^{\circ} \) with the vertical. (This means that the velocity vector of the rain with respect to truck makes 37 angle with the vertical.) Find the velocity of the rain with respect to (i) the truck and (ii) the Earth in units of \( \mathrm{km} / \mathrm{h} .\left(\sin 37^{\circ}=0.6, \cos 37^{\circ}=0.8\right) \) (a) \( 72,43.2 \) (b) (b) \( 112.5,187.5 \) (c) \( 112.5,67.5 \) (d) \( 54,43.2 \) (e) 150,120 3)A firefighter, a distance \( d=60 \mathrm{~m} \) away from a burning building,

3)A firefighter, a distance \( d=60 \mathrm{~m} \) away from a burning building,

(a) 0.144 km / s
(b) 1.7 km / s
(c) 0.6 km / s
(d) 1.2 km / s
(e) 0.85 km / s
2) A truck travels due west with a speed of 90.0 km / h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the truck make an angle of 37.0^∘ with the vertical. (This means that the velocity vector of the rain with respect to truck makes 37 angle with the vertical.) Find the velocity of the rain with respect to (i) the truck and (ii) the Earth in units of km / h .(sin 37^∘=0.6, cos 37^∘=0.8)
(a) 72,43.2 (b)
(b) 112.5,187.5
(c) 112.5,67.5
(d) 54,43.2
(e) 150,120
3)A firefighter, a distance d=60 m away from a burning building,
