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

You measure the velocity of a drag racer that accelerates with constant acceleration. You want to plot the data and determine th
Ivenika [448]

Answer:

a) Linear equation

Explanation:

Definition of acceleration

a=\frac{dv}{dt}\\

if a=constant and we integrate the last equation

v(t)=v_{o}+a*t

So the relation between the time and the velocity is linear. If we plot the velocity in function of time, the plot is a line, and the acceleration is the slope of this line.

guajiro [1.7K]

Answer:

the work done by the motor is 531,45 Joules

Explanation:

Using a sketch of the possible conditions, we need to find the distance that the block was moved, in order to find the work done by the electrical motor.

The sketch could be seen in the attached image.
