I think D
(b) first V2x = Vox = ____ m/s i Vox = 19.4cos52.5 second Y2 = height of cliff (negative) You want to find V2y V2y^2 = Voy^2 + 2ay[Y2-Yo]
Vo = 30 m/s Xo = 0 Yo = 0 theta = 42 ax = 0 m/s^2 i ay = -9.8 m/s^2 j Vox = 30cos42 Vox = ____ m/s i
Vo = 37 m/s Theta = 53.1 Xo = 0 m i Yo = 0 m j ax = 0 m/s^2 i ay = -9.8 m/s^2 j Vox = Vo * costheta = 37[cos(53.1)] = +22.2 m/s i Voy = Vo * sintheta = 37[sin(53.1)] Voy = +29.6 m/s j x1 = +44.4 m i
Position r = 4.5 i + (-4.9*.5^2) j To find position use theta=tan^-1(Vy/Vx)
Vo= 0m/s Vox = Voy = 0m/s > Xo = Xy = 0 a= 3 m/s^2 x is adjacent so Ax = 3cos(5.9) Ay = 3sin(5.9) Use X=Xo+Vox+1/2Axt^2 to get X1. Remember, Xo = 0...
You can use X=Xo+Vot+1/2at^2
Vpg = 1.65 m/s
to get time, you use the formula X=Xo+Vot+1/2at^2 where X=150
