Answer:
Vx = V0 cos 60 = V0 ./ 2 horizontal speed
Vy = V0 sin 69 = V0 * .866 = .866 V0 vertical speed
t = 107 / Vx = 214 / V0 time to travel 107 m
h = Vy t - 1/2 * g t*2 time to fall 1.7 m
-1.7 = .866 V0 * 214 / V0 - 4.9 * (214 / V0)^2 substituting
224400 / V0^2 = 187
V0 = (224400 / 187)^1/2 = 2=34.64 m/s
t = 214 / 34.64 = 6.178 stc
Check: h = Vy t - 1/2 g t^2
-1.7 = .866 * 34.64 * 6.178 - 4.9 * 6.178^2
-1.7 = -1.69

Answer:
272.05 K; 489.69 °R; -1.11 °C
Explanation:
Fahrenheit can be converted to degrees Celsius using the following formula:
°C = 5/9 x (°F - 32) = -1.11 °C
The temperature in Kelvin is calculated from the temperature in degrees Celsius as follows:
K = °C + 273.15 = 272.05 K
The temperature on the Rankine scale is calculated from Kelvin as follows:
°R = 1.8K = 1.8(272.05) = 489.69 °R
