Explanation:

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

The speed of sound in air at room temperature is about s=343 m/s. calculate this speed in miles per hour (mph). (1 mi = 1609 m.)

igor_vitrenko [27]

Given:
1 mi = 1609 m.

Also,
1 hour = 3600 s

Therefore
$343 \, \frac{m}{s} =(343 \, \frac{m}{s} )*(3600 \, \frac{s}{h}) *( \frac{1}{1609}\, \frac{mi}{m})= 767.433 \, \frac{mi}{h}$

Answer: 767.4 mph (nearest tenth)

g A rotating wheel requires 5.00 s to rotate 28.0 revolutions. Its angular velocity at the end of the 5.00-s interval is 96.0 ra

Setler [38]

Answer:

The angular acceleration of the wheel is 15.21 rad/s².

Explanation:

Given that,

Time = 5 sec

Final angular velocity = 96.0 rad/s

Angular displacement = 28.0 rev = 175.84 rad
