Answer:
θ = 41.80°
Explanation:
Given that
Mach number M= 1.5
We know that
M = u/c
Where c is the velocity of sound and u is the speed of plane
c= 340 m/s
So
u = 1.5 x 340 m/s
u = 510 m/s
We know that
Now by putting the values
θ = 41.80°
So the angle will be 41.80°.
Answer:
7.30523 m/s
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity
s = Displacement = 2.72 m
g = Acceleration due to gravity = 9.81 m/s² = a
Equation of motion
The speed which a quarter would have reached before contact with the ground is 7.30523 m/s
