Answer:
b) 0.5 m/s
Explanation:
let V be the averare speed of the object.
the average speed is given by:
V = total distance / total time
= (20+20)/(30+50)
= 0.5 m/s
Therefore, the average speed of the object is 0.5 m/s.
If he were to jump to 128,100 he would’ve had jump from the stratosphere
Answer:
The value of leaking rate in the question is repeated. By searching on the web I could find the correct value wich is 0.002h^2 m^3 /min.
The depth of the water has to be equal to 7.07 m in order to have a stationary volume.
Explanation:
In order to have a stationary water level the flow of water that comes into the tank (0.1 m^3/min) must be equal to the flow of water that goes out of the tank (0.002*h^2 m^3/min), therefore:
0.002*h^2 = 0.1
h^2 = 0.1/0.002
h^2 = 50
h = sqrt(50) = 7.07 m

Answer:
70 kg man
Explanation:
Let their velocities be v
Mass of the man= 70 kg
Hence, momentum of the man= 70v
Mass of the boy= 40 kg
Hence, momentum of the boy= 40v
70v > 40v
Clearly the momentum of the man is greater than that of the boy.
