The shock wave from the meteoroid in the lower atmosphere has a Mach angle of 0.948°.
(a) The meteoroid's speed 

Air sound wave speed 
Speed of the shock wave in Mach 

Hence, 0.948° is the Mach angle of the shock wave from the meteoroid in the lower atmosphere.
<h3>What is the speed of the meteoroid?</h3>
A meteoroid's speed can be loosely broken down into three categories: slow, medium, and fast.
- Slow meteors move around the sun at a leisurely pace of about 32 kilometers per second (20 miles per second).
- Medium-speed meteors travel around the sun at approximately 50 kilometers per second (30 miles per second),
- while fast meteors zoom past at over 120 kilometers per second (75 miles per second)!

Answer:
maximum speed 56 km/h
Explanation:
To apply Newton's second law to this system we create a reference system with the horizontal x-axis and the Vertical y-axis. In this system, normal is the only force that we must decompose
sin 10 = Nx / N
cos 10 = Ny / N
Ny = N cos 10
Nx = N sin 10
Let's develop Newton's equations on each axis
X axis
We include the force of friction towards the center of the curve because the high-speed car has to get out of the curve
Nx + fr = m a
a = v2 / r
fr = mu N
N sin10 + mu N = m v² / r
N (sin10 + mu) = m v² / r
Y Axis
Ny -W = 0
N cos 10 = mg
Let's solve these two equations,
(mg / cos 10) (sin 10 + mu) = m v² / r
g (tan 10 + μ / cos 10) = v² / r
v² = r g (tan 10 + μ / cos 10)
They ask us for the maximum speed
v² = 30.0 9.8 (tan 10+ 0.65 / cos 10)
v² = 294 (0.8364)
v = √(245.9)
v = 15.68 m / s
Let's reduce this to km / h
v = 15.68 m / s (1 km / 1000m) (3600s / 1h)
v = 56.45 km / h
This is the maximum speed so you don't skid
Answer:
v=22.5 m/s
Explanation:
Given that,
Initial speed, u = 0
Acceleration, a = 2.5 m/s²
Time, t = 9 s
We need to find how fast the car is moving i.e. its final speed. So,

u = 0
So,
v = at
v = 2.5 m/s²× 9
v=22.5 m/s
So, the final speed of the car is 22.5 m/s.
