A child rides the train at Disneyland which takes him in a loop around the amusement park at a speed of 3 m/s.

-- The speed is constant, because it's always 3 m/s.

<em>-- The velocity is changing because the direction is changing. </em>(This is one process that's called "acceleration".  Th e others are speeding up and slowing down.)

-- Strange as it may seem, the AVERAGE velocity for one whole loop around the whole park is zero !  Because velocity uses the distance between the start-point and the end-point, no matter what the route is from start to finish, and the ride ends in the same place where it began, so the distance between the start-point and end-point is zero.

The velocity is a vectorial quantity, whereas speed is a scalar quantity, meaning it depends on the direction!
As such, the velocity is changing because the direction is changing.

nadezda [96]

Answer:

distance when the weight is 8 ​kg is 26.66 cm

Explanation:

given data

distance d2 = 10 cm

weight w2 = 3 ​kg

weight w1 = 8 kg

to find out

distance when the weight is 8 ​kg

solution

we consider here distance d1 when weight is 8 kg

so equation will be

d1/d2 = w1/w2

d/10 = 8/ 3

so d = 8/3 × 10

so d = 26.66

distance when the weight is 8 ​kg is 26.66 cm
