A slower moving car is traveling behind a faster moving bus. The velocities of the two vehicles are: vCG = velocity of the Car r

elative to the Ground = +12 m/s vBG = velocity of the Bus relative to the Ground = +16 m/s A passenger on the bus gets up and walks toward the front of the bus with a velocity of vPB, where vPB = velocity of the Passenger relative to the Bus = +2 m/s What is vPC, the velocity of the Passenger relative to the Car?

Answer:

6m/s

Explanation:

A slower moving car is traveling behind a faster moving bus. The velocities of the two vehicles are: vCG = velocity of the Car relative to the Ground = +12 m/s vBG = velocity of the Bus relative to the Ground = +16 m/s A passenger on the bus gets up and walks toward the front of the bus with a velocity of vPB, where vPB = velocity of the Passenger relative to the Bus = +2 m/s What is vPC, the velocity of the Passenger relative to the Car?

When you are is in a car moving with 12m/s speed and then there is a bus moving with 16m/s in front of you. Of course, the bus is 4m/s faster than you. if a passenger in the bus stands and runs towards the front of the bus with a speed of 2m/s , he is 2m/s ahead +the 4m/s the bus was already ahead of you, mathematically

Vpg=speed of the passenger relative to the ground

Vpb=sped of the passenger relative to the bus

Vbc=speed of the bus relative to the car

Vbg=speed of the bus relative to the ground

Vpg=Vpb+Vbc

Vbc=Vbg+Vgc

so we can conclude that

Vpc=Ypb+Vbg+Vgc

Vpc=2+16-12

Ypc=6m/s

Your roommate is working on his bicycle and has the bike upside down. He spins the 60 cm
tigry1 [53]
Diameter = 60 cm, Radius = 60/2 = 30 cm = 30/100 = 0.3 m.

The pebble in the tread goes by 3 times every second.

This is the same as 3 times per second.

Recall the unit of frequency is Hertz or per second, s⁻¹

So 3 times per second, Frequency, f = 3s⁻¹ or 3 Hertz

For angular motion:

Angular speed, ω = 2πf

                         = 2*π*3

                         = 6π   rad/s

Linear speed, v = ωr =  6π * 0.3 = 1.8π m/s


Linear acceleration, a = v² / r

                               a = 1.8π * 1.8π / 0.3 = 10.8π²   m/s²

Angular acceleration α = a/r  = 10.8π² / 0.3 = 36π² rad/s²


Angular speed = 6π rad/s ≈ 18.840 rad/s

The linear speed of the pebble = 1.8π  m/s ≈ 5.655 m/s

The angular acceleration = 36π² rad/s² ≈ 355.306 rad/s²

The linear acceleration of the pebble = 10.8π²  m/s ≈ 106.592 m/s²
