V=d*t
Since d=75km=75000m
t=1.5h=3600*1.5= 5400s
=>V=75000*5400
=405000000m/s=4.05*10^8m/s
Sure what do u need help with
Answer:
F=507.7N
Explanation:
According to Newton's second law:

in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:

there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.

Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that

= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
El paquete golpearía el suelo a la velocidad de acuerdo con la aceleración de la gravedad. La velocidad también dependería de la masa del paquete.
