The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of -

5.60 m/s2 for 4.20 s, making straight skid marks 62.4 m long ending at the tree. With what speed does the car then strike the tree

The equation for speed is s=d÷t the distance=62.4m and the time=4.20s so 62.4÷4.20= 14.857

A stationary siren on a firehouse is blaring at 81Hz. Assume the speed of sound to be 343m/s. What is the frequency perceived by

inn [45]

For a stationary siren on a firehouse is blaring at 81Hz. Assume the speed of sound to be 343m/s, the frequency perceived is mathematically given as'

F=81.721Hz

<h3>What is the frequency perceived by a firefighter racing toward the station at 11km/h?</h3>

Generally, the equation for the doppler effect is mathematically given as

$F'=\frac{vs+v}{vs}*f$

Therefore

F=81(343+3.05556)/343

F=81.721Hz

In conclusion, the frequency is

F=81.721Hz
