Answer:
w =3416 rad/min
Explanation:
The angular speed of the wheels in radians can be defined as follows:
where
w = angular speed
r = radius of the wheel
s =distance traveled per minute
in this case we have
r = 34/2 inches = 17 inches
s = (55 mi/hr) (5280 ft/mi) (12 in/ft) (1hr/60min) = 58,080 inches/min
Therefore, w = 58,080/ 17 = 3416 rad/min
<em>Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.</em>

Answer:
The Average speed = 15000 / 0.005 = 3000000 m/s
Explanation:
- Average speed can be calculated by dividing the total distance covered by the total time.
Average speed = Total Distance / Total time
Given
- Total distance = 15km = 15(1000) = 15000 m
- Total time = 5 ms = 0.005 seconds
Thus,
Average speed = Total Distance / Total time
Average speed = 15000 / 0.005 = 3000000 m/s
Answer:
2.8A
Explanation:
To calculate the total amplitude (when both pulses meet), we need to add up the amplitudes of each pulse. Since A is the amplitude of the first pulse, and we can call B the amplitude of the second pulse and C the total amplitude, we have that A+B=C=3.8A, which means that B=3.8A-A=2.8A, which we have already said is the amplitude of the second pulse.
Explanation:
What is the difference between the displacement of the photographer flying from FL to CA and the displacement of astronauts flying from CA back to FL? The displacements have opposite directions. Car 'A' travels from New York City to Miami ata speed of 25 m/s.
