Answer:
0.267
Explanation:
The Mach number is given by the following formula:
where v = speed of the object
c= speed of air
Ma = Mach number
From the data:
Velocity of the object = 91.44 m/s
Velocity of air = 343 m/s
Therefore, the Mach number is given by the following formula:
Ma =
= 0.267

I would recommend a truck. It can haul heavy things.
Answer:
v = 21.409 m/s
Explanation:
Given data:
Total weight of the platform and weight together, W = 900 N
Diameter of the water jet = 5 cm = 0.05 m
Now,
the force exerted by the water jet is balancing the platform
also,
Force exerted by the water jet = ρAv²
where,
ρ is the density of the water = 1000 kg/m³
A is the area of the outlet of the jet =
or
A = 0.00196 m²
v is the velocity of the jet
thus,
W = ρAv²
or
900 = 1000 × 0.00196 × v²
or
v = 21.409 m/s
Hence, the velocity of the jet is 21.409 m/s
