Which are characteristics of electromagnetic waves? Check all that apply.
.
Waves with a higher frequency have a shorter wavelength.
They all move at the same speed.
They can travel through space.
To start, we need to know the formula for centripetal acceleration
In this problem, we know that the speed of the vehicle is 95 km/hr
We will need to convert that speed into m/s
95 km/hr = 26.3889 m/s
Second, we know that the diamater of the circular track is 1 km.
To find radius, we just take half of the diameter, which makes the radius 500 meters.
Now we have:
Velocity = 26.3889 m/s
& Radius = 500 meters
Plugging this into the centripetal acceleration formula yields us
a = (26.3889)^2/500 = 1.39 m/s^2
Newton's 2nd law of motion says:
Force = (mass) x (acceleration).
In order to accomplish the task described in the question,
you would need
Force = (20 kilograms) x (the desired rate of acceleration) .
