143m/s if you just perhaps by what you know you'll figure it out
At -40.
-40 gives the same reading for Fahrenheit and Celsius scale.
Answer:
what is the action and reaction ?
Explanation:
K.E = 1/2*m*v^2 = 1/2(500)(3)^2 = 2250 J
m*g*h = 500(9.8)(30) = 147000 J
2250 + 147000 = 149250
It probably is the actual answer.
