A ball travels around a roulette wheel with a radius of 0.4 m at a tangential velocity of 1.1 m/s. What is the period of the ball as it travels around the wheel?

T = 2.28 s

Explanation:

Given that,

The radius of the wheel, r = 0.4 m

The tangential velocity of the wheel, v = 1.1 m/s

We need to find the period of the ball as it travels around the wheel. Let it is T. We know that, the tangential speed is given by :

So, the period of the ball is equal to 2.28 s.

what was the answer?

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
