The deceleration of the rocket sled if it comes to rest in 1.1 s from a speed of 1000 km/h is .
The acceleration in opposite direction is known as the deceleration. Basically the deceleration is negative value of the acceleration since the negative sign depicts its opposite in direction.
The given data:
time, t = 1.1 s
initial speed, u = 1000 km/h =
final speed, v = 0 m/s
So we will be using the equation of motion, that is,
v = u + at
Hence , the deceleration of the rocket is .

Answer:
19.33°C
Explanation:
To find the value of T you use the following formula:
v: speed of sound
To calculate v you use:
λ: wavelength = 0.651m
f: = 545Hz
by replacing :
Finally, by replacing in the first formula you obtain:
T = 19.33°C
