Disregarding Air resistance, and launched at a 45o angle to the horizontal towards the right: 200 lbs = 91 kg 30 feet = 10m approximately d = vhorizontal * t = vhorizontal * (2vvertical /g) = 2v2horizontal/g = 10m 2v2/ (9.8m/s2) = 10m 2v2 = 98 (m2/s2) v2 = 49 (m2/s2) vhorizontal= 7 m/s V = (v2horizontal + v2vertical)0.5 = 7(1.41421) = 9.8995 m/s at the 45o Disregarding Air resistance, and launched at a 45o angle to the horizontal towards the right: 200 lbs = 91 kg 30 feet = 10m approximately d = vhorizontal * t = vhorizontal * (2vvertical /g) = 2v2horizontal/g = 10m 2v2/ (9.8m/s2) = 10m 2v2 = 98 (m2/s2) v2 = 49 (m2/s2) vhorizontal= 7 m/s V = (v2horizontal + v2vertical)0.5 = 7(1.41421) = 9.8995 m/s at the 45o or 21.175 mph
